-> **Branches / PRs (current working branch: `feature/android-release-prep`).**
-> - `development` — has the **legal-documents track**, merged via **PR #253** (green, deployed to the
->   test contour). `/privacy/`, `/eula/`, `/offer/` are live there, bilingual RU/EN.
-> - `feature/android-release-prep` — the **release-prep hygiene**, **PR #254 OPEN, green, NOT merged**
->   (the owner chose to hold the merge). It is branched off `development`, so it also contains the

->
-> **Done this session.**
-> - **Legal documents** (satisfies the RuStore *hosted privacy-policy URL* prerequisite): authored
->   `ui/legal/{privacy,eula,offer}_{ru,en}.md`; served as **bilingual (RU/EN)** standalone pages by the
->   render sidecar at `/privacy/`, `/eula/`, `/offer/` via the shared `ui/src/lib/offer.ts`
->   `renderLegalHtml`, with a client-side **language + theme switcher** (🌐 + ☼/☾, no "back", default
->   Russian + persisted, mirroring the landing). The offer's EN view **transliterates** the Russian

->   **Locked legal decisions — do NOT re-litigate:** seller **INN `290210610742`**; EULA §14 leads
->   with **RF law + jurisdiction** as residence tiers (France / England&Wales retained as foreign
->   tiers); the "only the English version is legally binding" clause is **removed**; data collection is
->   kept but **scoped to voluntary/support provision** (passport/payment/ID only when the user provides
->   them); «Компания» is not shout-cased; the offer's EN catalog product names are **transliterated**
->   (owner-chosen), while its headings/columns are translated.
-> - **Release-prep hygiene (PR #254):** de-anchored `ANDROID_PLAN.md` from all code/docs — **no
->   reference to this file remains anywhere outside it**; **re-enabled the `android-build` workflow**
->   (`.gitea/workflows/android-build.yaml.disabled` → `.yaml`; it is `workflow_dispatch`-only + gated
->   `if master`, so it never auto-runs; the CI host already has the Android SDK at `/opt/android-sdk`);
->   added [`docs/ICONS.md`](docs/ICONS.md) (the single-master icon/logo format reference).
->
-> **Remaining to release (owner-gated unless the agent is named).**
-> 1. **Icon rebrand — DONE.** The SVG-tracer export failed, so the icon was designed **collaboratively
->    from scratch** (wooden «Э» tile + ✻ subscript, Spectral Bold). The construction is fully specified
->    in fractions of the side in [`docs/ICON_BRANDBOOK.md`](docs/ICON_BRANDBOOK.md), with the reference
->    generator + pinned font + masters in [`assets/icons/brand/`](assets/icons/brand/). One master →
->    the whole set sliced by `brand/build-set.mjs` (+ `build-android-res.mjs`): web (favicon light+dark,
->    apple-touch, PWA any + maskable, og-image reskinned to «Эрудит» / Игра в слова), the Capacitor
->    layers `ui/assets/{icon,icon-foreground,icon-background}.png`, the Android launcher res (all
->    densities, **no inset**, **+ monochrome** themed layer), and manual-upload art (`brand/{vk,tg,store}`).
->    Primary variant **light**; dark where the platform can theme (favicon.svg). The old LiberationSans
->    generator (`assets/icons/build/`) is removed; targets are mapped in `docs/ICONS.md`.
-> 2. **Merge PR #254** → `development` (owner approval), then **promote `development` → `master`** and
->    **tag `vX.Y.Z`** for the release (the version stamps the APK `versionName`/`versionCode` and the
->    `X-Client-Version` header).
-> 3. **Release keystore.** OWNER generates it (`keytool -genkeypair -v -keystore erudit-release.jks
->    -alias erudit -keyalg RSA -keysize 4096 -validity 10000`), base64-encodes it, sets the four Gitea
->    **secrets** `ANDROID_KEYSTORE_BASE64` / `ANDROID_KEYSTORE_PASSWORD` / `ANDROID_KEY_ALIAS` /
->    `ANDROID_KEY_PASSWORD`, and backs the `.jks` up **off-host** (loss ⇒ the app can never be updated).
->    The AGENT provides the exact commands on request. Without the secrets the workflow builds an
->    UNSIGNED APK (a dry run still proves the pipeline).
-> 4. **RuStore developer account.** OWNER (verified legal entity or self-employed / самозанятый). Gates
->    publication, not the build.
-> 5. **Dispatch the signed build.** AGENT: on `master`, dispatch `android-build` (`confirm=build`) via
->    `tea`, watch to green, retrieve the signed APK artifact (verify Gitea 1.26 `upload-artifact@v4` at
->    the dispatch).
-> 6. **On-device smoke.** OWNER installs the signed APK and runs the airplane-mode first-launch
->    checklist (`docs/TESTING.md`). The AGENT can pre-run the emulator smoke.
-> 7. **Store listing.** Reserve `ru.eruditgame.app`, title «Эрудит», RU description, phone screenshots,
->    icon / feature graphic, age rating, the **privacy-policy URL `https://erudit-game.ru/privacy/`**
->    (now available), the content declaration.
-> 8. **Upload to RuStore.** OWNER. After publication, set the `ANDROID_RUSTORE_URL` Gitea variable to

-## E10 — Multi-shop direct rail + ИП fiscalization
-
-**Status:** DONE (merged — the multi-shop PR) · **Release 2+ (post-launch, backend-first)** · depends on: E5 (intake/`Fund`,
-the `robokassa` adapter, the Result callback), E7 (the per-user report — channel breakdown) ·
-mechanics: PAYMENTS §9, §12; decisions D41 (rev), D42–D44.
-
-**Goal.** Split the single Robokassa `direct` rail into **per-channel merchant shops** (web,
-android; ios later) — separate merchant accounts / withdrawal / accounting and a per-channel
-breakdown in the E7 report — while keeping **one `direct` wallet** (D42). Land the wallet/identity
-rules the native apps need (email-only anchor, D43) and revise fiscalization for the owner's move
-to **ИП / 54-ФЗ** (D41 rev). All **additive / contour-safe** and **money-live** → expand-contract
-throughout.
-
-**Locked decisions (owner interview 2026-07-14): D41 (rev), D42, D43, D44.** No wallet-model /
-spend-wall change; the split is merchant-account routing under one `direct` segment. Route the shop
-by the **trusted** `X-Platform` subtype, never a client field; unknown → `web`.
-
-**B1 — Config: one shop → a set of shops.**
-
- `robokassa.Config` (single) → a **shops registry** keyed by channel (`web`, `android`; `ios`
-  later), each 4 fields (`MerchantLogin`/`Password1`/`Password2`/`IsTest`). New env
-  `BACKEND_ROBOKASSA_WEB_*`, `BACKEND_ROBOKASSA_ANDROID_*`.
- **Expand-contract, no flag-day:** the legacy `BACKEND_ROBOKASSA_*` seeds the `web` shop; add the
-  new vars; retire the legacy set after the prod rollout sets the split vars. `validate()`: a shop
-  with a login must carry both passwords (mirror the current check), per shop.
- Config/README + `deploy/.env.example` + the deploy ansible vars.
-
-**B2 — Route the shop by channel (intake).**
-
- `handleWalletOrder` `SourceDirect` branch: pick the shop by `cxt.Subtype` (`web`/`android`;
-  unknown → `web`). Build the payment request from that shop. The subtype rides the trusted
-  gateway-injected `X-Platform` (`<kind>/<subtype>`, `parsePlatformHeader`) — no spoofable client
-  field. **Verify the gateway emits `direct/android` for the native build**; if it sends a bare
-  `direct/`, add the android subtype (small gateway change).
- Record the chosen `shop` on the order (feeds B5).
-
-**B3 — Per-shop Result callbacks.**
-
- The callback must select the right `Password2` → each shop gets its own Result URL:
-  **per-shop public edge routes** (mirror the existing single Robokassa Result route, e.g.
-  `…/result/web`, `…/result/android`), each forwarded to the backend and verified with that shop's
-  config, then the same `Fund` (source stays `direct`). Add the routes to the **Caddyfile
-  `@gateway` matcher** (else they fall to the landing catch-all) **+ a CI probe per route**.
- Keep the legacy single route alive (shop = `web`) through the expand-contract window until the
-  cabinet Result URLs are cut over.
-
-**B4 — ИП fiscalization (D41 rev) — RESOLVED (owner 2026-07-14): cabinet-side only.** The owner keeps
-Robokassa's cabinet auto-fiscalization (a generic чек is acceptable for the ИП); the optional
-itemized-`Receipt` / `Email` code below is **dropped** — not needed. (Kept for context.)
-
- **Owner/cabinet:** enable the 54-ФЗ cloud kassa in the Robokassa ЛКК (kassa + ОФД + СНО).
-  Required for ИП regardless of code.
- **Code (optional, itemized чеки):** send a one-line `Receipt` (pack name, qty 1, `sum`, `tax`
-  per СНО, `payment_object`/`payment_method`) + the customer `Email` (the D36 confirmed anchor) in
-  the payment request; extend the signature to `MerchantLogin:OutSum:InvId:Receipt:Password1`
-  (URL-encode `Receipt`). One line fits the current GET redirect; POST-form only as a URL-length
-  fallback. One feature, all shops. **Sequenced last** — the split (B1–B3, B5, B6) needs no
-  fiscalization. Supersedes the E5 §12 shop-side НПД receipt note.
-
-**B5 — Channel in the report (D44).**
-
- Additive `shop` column on the order (default `web` / backfill from `origin`); a per-channel
-  breakdown in the E7 per-user report (D40). Expand-contract migration (nullable/defaulted column),
-  **contour-safe** (a schema touch → note the contour `DROP SCHEMA` step in `PRERELEASE.md`).
-
-**B6 — Tests + docs.**
-
- unit: the `robokassa` shops registry + per-shop `VerifyResult` (right `Password2`);
-  signature-with-`Receipt` (B4); intake shop routing by subtype (web/android/unknown→web).
- integration: order→per-shop callback→credit (each route), a duplicate credits once, an expired
-  order still honoured; the `shop` recorded + reported.
- docs: `PAYMENTS.md` (+`_ru`) the multi-shop topology + the ИП/54-ФЗ receipt revision;
-  `deploy/README` + `.env.example` the new vars + the per-shop Result routes + probes;
-  `PRERELEASE.md` the `shop` column contour step.
-
-**Done-criteria.** A `direct/web` order pays through the web shop and `direct/android` through the
-android shop, each verified with its own `Password2`, both crediting one `direct` wallet exactly
-once; the E7 report breaks payments down by channel; the split stays contour-safe (the legacy shop
-still works until the cabinet cutover). B4 (fiscalization) verified when the owner's ИП/ОФД/СНО are
-live.
-
-**Notes/risks.** Edge routes fall through if not in the Caddyfile `@gateway` matcher — add a CI
-probe (field note). The prod rolling deploy skips caddy on config-only changes — force-recreate on a
-Caddyfile change. Money-live: expand-contract only, image rollback DB-safe. Confirm the gateway
-emits `direct/android` for the native build before relying on subtype routing.

-## E11 — Payment availability kill switch + per-account override
-
-**Status:** DONE · **Release 2** · depends on: E5 (intake/order), E7 (admin console) · mechanics:
-PAYMENTS §9; decisions D45, D46.
-
-**Delivered.** An operator disables purchases live from `/_gm` — a whole rail/channel or one account
-— and the user sees a localized reason on the next purchase attempt. Motivation (owner): real apps
-show broken payments with no explanation; this gives ops a live switch + a clear user message.
-
- **Rail kill switch** — `payments.rail_status` (per rail `direct:web` / `direct:android` / `vk` /
-  `telegram`): `enabled` + a per-language message, edited on the catalog page. **Fail-open** (no row
-  ⇒ enabled, so payments are never accidentally killed). The intake gate — `CanPurchase` in
-  `handleWalletOrder`, before the order — returns `payment_unavailable` + the localized message;
-  orthogonal to the security gates.
- **Per-account override** — `payments.account_payment_override` (a row only for non-default; default
-  = no row, cleared by delete): allow / deny / default, edited on the user card. `allow` bypasses
-  **only** the ops rail switch, never the security gates (D46).
- **Wire** — the message rides an additive `ExecuteResponse.message` (envelope layer,
-  frozen-contract-safe; the gateway forwards a backend domain-error message via `DomainMessage`); the
-  client reads it into `GatewayError.message` and shows it on a `payment_unavailable` buy attempt.
- **Tests** — the pure gate `PurchaseGate` (unit, TDD); the store + gate + override end-to-end
-  (integration, migration `00016`); the client (svelte-check / vitest). **Docs** — PAYMENTS (+`_ru`),
-  decisions D45 / D46.
-
-**Contour-safe:** additive migration (two new tables, no wipe); the wire add is additive; fail-open,
-so nothing is disabled until an operator acts.

-The whole shipped icon set is sliced from **one master** — see

-outputs, and [`../../docs/ICON_BRANDBOOK.md`](../../docs/ICON_BRANDBOOK.md) for how the

-[`../../docs/ICONS.md`](../../docs/ICONS.md).
+The favicon set and the `og:image` link-preview card for the public landing
+(`ui/landing.html`) and the SPA shell (`ui/index.html`). Same design language as the
+[VK loading-screen logo](../vk/README.md): the wooden Erudit «Э» tile (score `8`),
+with the wordmark on the app's dark board green (`ui/src/app.css` tokens).
+
+| Output (committed to `ui/public/`) | Purpose |
+|------|---------|
+| `favicon.svg` | Vector favicon, transparent; tile + «Э» only (the score is illegible below ~32 px). |
+| `favicon.ico` | 32×32 PNG-in-ICO fallback (also answers the browsers' blind `/favicon.ico` probe). |
+| `apple-touch-icon.png` | 180×180 opaque full-bleed tile; iOS masks its own corners. |
+| `og-image.png` | 1200×630 card: tile + «Эрудит / Скрэббл — игра в слова». Referenced absolutely as `https://erudit-game.ru/og-image.png`. |
+
+## How it works
+
+`build/extract.js` extracts the needed glyph outlines (tile glyphs + every wordmark
+character) from LiberationSans (Arial-metric, the game's font stack) with their
+advance widths into `build/glyphs.json` (committed). `build/generate.js` composes
+plain SVG from those outlines — no font is needed at generation time — writes
+`favicon.svg` and rasterises the PNG/ICO outputs by screenshotting the SVGs with the
+`ui` package's Playwright chromium (`@playwright/test`); the `.ico` container is
+assembled in-script (a single PNG entry). Raster bytes therefore depend on the
+installed chromium version; the SVG sources are deterministic.
+
+## Regenerate
+
+Requirements: Node ≥ 18, `ui` installed (`pnpm install`, provides Playwright).
+`extract.js` additionally needs `opentype.js` (`npm i opentype.js`); **`generate.js`
+needs no extra packages**.

 ```sh
-cd brand
-npm i opentype.js
-node build-set.mjs          # web (ui/public) + Capacitor layers (ui/assets) + vk/ tg/ store/
-node build-android-res.mjs  # Android launcher resources (all densities + monochrome)
-```
+cd assets/icons

-> The earlier `build/` pipeline (LiberationSans glyph outlines → favicon/apple-touch/OG)
-> was replaced by `brand/` when the icon was rebranded onto the Spectral «Э» master.
-> The separate VK loading-screen animation lives in [`../vk/`](../vk/) and is unrelated.
+# 1. (optional) re-extract the glyphs — only if the font or the wordmark changes:
+#    default font: /usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf
+node build/extract.js [/path/to/font.ttf]      # -> build/glyphs.json
+
+# 2. regenerate everything in ui/public/:

-# Erudit app-icon — brand book
-
-The single source of truth for **how the Erudit icon is constructed**. It is written to
-be reproducible *from words alone*: a designer with this document and the Spectral font
-can rebuild the icon exactly, at any size, without pixel-matching anything.
-
-Two rules make that possible:
-
-1. **The icon is a square.** Every size and position below is a **fraction of the
-   square's side** (equivalently, a percentage). Nothing is in pixels. Draw the square
-   at whatever resolution you need and scale each value to it.
-2. **The origin is the top-left corner.** `x` grows right, `y` grows down. So "center
-   `48.1% / 49.2%`" means a point `0.481·side` from the left and `0.492·side` from the top.
-
-The companion generator in [`../assets/icons/brand/`](../assets/icons/brand/) is the
-machine version of this exact spec (`build-icon.mjs`, where each constant is the same
-fraction printed here). The `docs/ICONS.md` map covers the *opposite* concern — which
-files/sizes we slice this master into for each platform.
-
-## Anatomy
-
-![Construction scheme](../assets/icons/brand/icon-construction.png)
-
-Bottom-to-top the icon is six layers: **tile → wood grain → light sheen → shadow →
-letter «Э» → star ✻**. The letter and star are always drawn last, at full ink colour;
-the grain and the two gradients only ever touch the background.
-
-## Palette
-
-The icon ships as a **light** and a **dark** variant (a matched pair — the light tile
-carries dark ink, the dark tile carries light ink). Each variant uses four colours.
-
-| Role | Light | Dark |
-|------|-------|------|
-| **Tile** — the wooden body | `#e6b053` | `#4a3316` |
-| **Ink** — the «Э» and the ✻ | `#5a3a12` | `#f2d9a0` |
-| **Grain** — the vertical stripes | `#d8a54e` | `#432e14` |
-| **Sheen** — diagonal light | white, α 0 → 15 % | white, α 0 → 15 % |
-| **Shadow** — diagonal dark | black, α 15 → 0 % | black, α 15 → 0 % |
-
-The grain colour is intentionally close to the tile — a hair darker — so the stripes
-read as wood texture, not as stripes.
-
-## 1 — Tile
-
-A **square with rounded corners**, corner radius **17 %** of the side, filled with the
-**Tile** colour. This is the whole background; there is no separate outer frame or
-border. Corners are baked at 17 %; platform masks (iOS/Android) may round further on top.
-
-## 2 — Wood grain
-
-Subtle vertical planks over the tile:
-
- Divide the width into **6 equal columns** (each `1/6` of the side wide).
- On the **right edge of each column**, draw one **vertical stripe**, width **`1/32` of
-  the side** (≈ 3.1 %), running the full height.
- Move the **whole set of six stripes left** by **`1/16` of the side** (= two stripe
-  widths).
- **Tilt every stripe 4°** (clockwise, about its own centre).
- Draw the stripes **past the top and bottom edges** so the tilt leaves no empty corners,
-  then **clip the whole set to the tile** (so the rounded corners stay clean).
- Colour: **Grain**.
-
-## 3 — Light sheen · 4 — Shadow
-
-Two linear gradients along the **same diagonal**, from the **bottom-left corner to the
-top-right corner**, each clipped to the tile and sitting **above the grain, below the
-letter**:
-
- **Sheen** — white. Fully transparent at the bottom-left, rising to **15 % opacity** at
-  the top-right. Brightens the top-right.
- **Shadow** — black. **15 % opacity** at the bottom-left, fading to transparent at the
-  top-right. Deepens the bottom-left.
-
-Together they give the tile a lit-from-the-top-right, resting-in-shadow-at-the-bottom-left
-sense of depth. Both percentages are a tuning knob (`--sheen`, `--shade`).
-
-## 5 — The letter «Э»
-
- Typeface: **Spectral, Bold** (SIL OFL; pinned in the brand folder).
- Glyph: the Cyrillic capital **«Э»** (U+042D).
- Size: scale the glyph so its **ink bounding box is 60.5 % of the side tall** (its width
-  then follows the font — about 53.2 %).
- Position: place the **center of that bounding box** at **48.1 % / 49.2 %** (just up and
-  left of the icon center).
- Colour: **Ink**.
-
-## 6 — The star ✻
-
-A **six-spoke teardrop asterisk** (the "score" mark that replaces a tile's point number):
-
- Each spoke tapers to a **point at the center** and ends in a **round bulb**; a central
-  disc equal to a bulb fuses the six spokes.
- Outer diameter: **17.3 % of the side**.
- Bulb radius (and the central disc): **22 % of the star's radius**.
- Position: center at **78.8 % / 78.8 %** — tucked to the lower-right of the «Э», like a
-  subscript, with a clear gap from the letter.
- Colour: **Ink**.
-
-Spectral has no ✻ glyph, so the star is **drawn geometrically**, not set as type. The exact
-construction is in `build-icon.mjs` (`starPath`).
-
-## Composition intent
-
-The «Э» and the ✻ are treated as **one group**. Its combined bounding box measures
-about **65.9 % × 68.6 %** of the side, and it is placed so its **bottom-right corner sits
-at 87.5 % / 87.5 %** of the icon (the lower-right corner of an inner `12.5 % … 87.5 %`
-safe square). That is what pushes the composition down-and-right and leaves the star room
-in the corner. When re-deriving positions, this is the anchor to preserve.
-
-> This bottom-right bias suits a **full-bleed** icon (iOS / PWA / favicon, which show
-> almost the whole square). Android crops more, so it uses a **separate two-layer build**
-> — see the next section. The master itself is never moved for Android.
-
-## Android adaptive icon (two layers)
-
-Android icons are **108×108 dp** and the OS applies its own mask (circle, squircle,
-rounded square…). Only the **inner 66 dp = 61 % of the side, centred** is guaranteed
-visible under every mask; the outer ~1/6 ring is used for the mask and motion effects.
-So Android is **not** the full-bleed master — it is built as two layers:
-
- **Background** — the tile with wood grain and the light/shadow gradients, **full-bleed
-  and square** (no rounded corners; the OS supplies the shape). It fills the whole 108 dp
-  layer, so the sacrificial outer ring is just more wood.
- **Foreground** — **only the «Э» + ✻**, transparent, **re-placed** to sit safely inside
-  the mask:
-  - «Э»: box height **53.9 %**, box center **52.3 % / 49.5 %**.
-  - ✻: outer diameter **13.2 %** (smaller than the master's), center **76.3 % / 72.7 %**,
-    tucked closer to the letter.
-  - The mark is centred, then nudged **right 8 % / down 3 %** so it reads optically
-    centred under the round mask, and the whole group fits within the **61 % safe zone**.
-
-Everything else (palette, grain, gradients, star construction) is identical to the master.
-
-## Variants in use
-
-The **light** variant is the primary icon (launcher, favicon, apple-touch, PWA). The
-**dark** variant is shipped in addition wherever the platform can pick by appearance
-(e.g. an SVG favicon via `prefers-color-scheme`). Where a platform allows only one icon,
-use **light**.
-
-## Reproduce
-
-```sh
-cd assets/icons/brand
-npm i opentype.js
-# full master (iOS / PWA / favicon), either variant:
-node build-icon.mjs --variant light --layer full        > icon-light.svg
-# Android adaptive layers:
-node build-icon.mjs --variant light --layer background   > icon-light-android-background.svg
-node build-icon.mjs --variant light --layer foreground   > icon-light-android-foreground.svg
-# the construction figure:
-node build-icon.mjs --variant light --scheme             > icon-construction.svg
-node render-png.mjs  icon-light.svg  icon-light.png  1024   # any size
-```
-
-`--layer` is `full` (default), `background`, or `foreground`. All outputs are committed
-alongside the generator in [`../assets/icons/brand/`](../assets/icons/brand/).

-  **Robokassa** (direct) — фискальный чек по **54-ФЗ** через облачную кассу Robokassa

-  по СНО; иначе — обобщённый дефолт-чек из кабинета. `Receipt` входит в подпись
-  (`MerchantLogin:OutSum:InvId:Receipt:Пароль#1`, URL-кодируется), одна позиция влезает в
-  текущий GET-redirect (POST-форма — фолбэк на длину URL). Источник чеков один — ИП/касса,
-  независимо от числа магазинов Robokassa. **VK** — процессит Голоса через налоговую сам.
-  **TG Stars** — вне рублёвого фискального контура (принимаем, чек не формируем). ОРД по
-  VK-рекламе — на стороне VK. *(Не юрконсультация — схему по 54-ФЗ/СНО владелец сверяет с
-  бухгалтером.)*
- **D42. Direct-рельс — несколько магазинов Robokassa = маршрутизация merchant-аккаунтов по
-  каналу при едином кошельке.** Кошелёк `direct` остаётся один. Отдельные магазины Robokassa
-  (web, android; ios — позже) различаются только кредами / Return-URL / учётом и **все
-  зачисляют в сегмент `direct`**. Модель кошельков, стенка трат и origin бенефитов не меняются.
-  Магазин выбирается по трастовому сигналу канала (`X-Platform` вида `<kind>/<subtype>`:
-  `direct/web`, `direct/android`), а не по подделываемому клиентскому полю; неизвестный подтип
-  → магазин `web` (безопасный дефолт). Зачисление от выбора магазина не зависит (всегда
-  `direct`), поэтому ошибка маршрутизации влияет максимум на учёт, не на деньги.
- **D43. Standalone-приложения (Android, iOS) — вход только по email; покупка требует
-  email-якорь.** В нативной сборке доступны только guest + email: VK ID-логин (full-page
-  redirect на `id.vk.com`) не возвращается в Capacitor, TG Login Widget в WebView ненадёжен —
-  это уже действующая реальность сборки, не новое ограничение. Direct-покупка требует
-  подтверждённого email-якоря (D36) — он же адрес фискального чека (D41); гость не покупает.
-  Отдельный сегмент `apple` НЕ заводим: iOS-standalone — тот же `direct`-контекст, внешний гейт
-  (Robokassa) фондирует единый `direct`. Сегмент `apple` со стенкой (по образцу vk/tg)
-  понадобился бы только при Apple IAP (StoreKit) — отложено до решения по iOS; и identity-kind
-  `apple→direct`, и отдельный сегмент — аддитивны, без риска, делаются на месте.
- **D44. Канал платежа хранится на заказе для раздельного учёта/отчёта.** Заказ получает поле
-  `shop` (web/android/…) — аддитивная колонка. Используется в финансовом отчёте (D40) для
-  разбивки «из какого магазина/канала платёж». На зачисление и на сегмент кошелька не влияет
-  (всегда `direct`, D42).
- **D45. Рубильник платежей per-rail + локализованное сообщение.** Оператор выключает покупки на
-  рельсе/канале (`direct:web`/`direct:android`/`vk`/`telegram`) живьём из `/_gm` (таблица
-  `payments.rail_status`, редактируется на странице каталога). **Fail-open:** нет строки → рельс
-  включён (случайно не убить платежи). Выключенный рельс на попытке покупки возвращает
-  `payment_unavailable` + сообщение админа на языке юзера (RU/EN; пусто → встроенное «временно
-  недоступно»). Сообщение едет клиенту через аддитивное `ExecuteResponse.message` (envelope-слой,
-  frozen-contract-safe). Гейт ортогонален security-гейтам.
- **D46. Per-user override покупок (allow/deny/default).** На карточке юзера (`/_gm`) —
-  переопределение на аккаунт: `allow` (всегда разрешить), `deny` (всегда запретить), `default` (по
-  рельс-рубильнику). Хранится в `payments.account_payment_override` строкой только для не-default
