-## 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**.
+The whole shipped icon set is sliced from **one master** — see
+[`brand/`](brand/) for the reference generator, the pinned font and the committed
+outputs, and [`../../docs/ICON_BRANDBOOK.md`](../../docs/ICON_BRANDBOOK.md) for how the
+mark is constructed. The per-platform target map (which file goes where) is in
+[`../../docs/ICONS.md`](../../docs/ICONS.md).

-#    default font: /usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf

+# 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

+node render-png.mjs  icon-light.svg  icon-light.png  1024   # any size

Mirror the existing /telegram/ launch-error behaviour: render a compact, shareable, privacy-safe diagnostic screen instead. - Boot: a new branch `onVKPath() && !insideVK()` sets app.launchError and stops the fall-through, the VK counterpart of the /telegram/ diagnostic guard. - Diagnostic (passive, no VK Bridge round-trip): reads the URL launch-parameter NAMES (never the `sign` value — auth material), whether the URL was signed, `vk_platform`, the iframe/referrer context, plus the shared client-environment lines. VK signs the launch URL at load, so — unlike Telegram's initData — the parameters never arrive late; hence the VK screen offers Share only, no Retry. - Generalise the screen: TelegramLaunchError.svelte -> LaunchError.svelte, which renders a neutral pre-formatted report and a per-platform title, with Retry gated on a `retry` flag (Telegram true, VK false). app.launchError is now a neutral LaunchDiag { platform, report, retry }. - New lib/launchdiag.ts holds the shared pieces both platforms reuse: the LaunchDiag shape, the client-environment lines, and the query field-NAME reader (moved out of telegram.ts so VK does not duplicate them). Tests: pure vkDiagLines units, incl. a guard that the `sign` value never leaks into the report. i18n: launch.errorTitleVk (en/ru).

Root cause: the gateway email class (auth.email.request + auth.email.login, keyed per IP, 5/10min burst 2) trips on the third event, which in the natural "request code -> wrong code -> correct code" sequence is the correct-code login. The gateway returns ResourceExhausted; the client mapped it to 'rate_limited', which retry.ts classified as retryable + a connection code, so exec() called reportOffline(). That pushes the net-state machine into connecting, whose recovery probe is an authenticated profile.get -- but the login screen has no session, so the probe can never succeed and the machine latches offline. The transport kill switch (assertOnline) then refuses the very login that would fix it, and because the IP's email bucket refills only 1 token / 120s, each fresh attempt after a restart is rate-limited again -> offline again. Fix (client, narrow -- the trigger): - A rate-limit is no longer treated as connectivity. retry.ts no longer marks 'rate_limited' retryable or a connection code, so exec() never reports it offline; it surfaces as the existing error.rate_limited "slow down" message. Not auto-retrying it also stops the ~20s button freeze and avoids feeding the gateway's ban tripwire with 6 extra rejections per attempt. Fix (server): - Raise the email-code burst 2 -> 4 so the honest request + a mistyped code + the correct one is not throttled mid-login. Defence-in-depth over the backend's own per-code guards (5-attempt cap + 15-min TTL + send throttle). Tests: retry classification units updated to the new semantics; a gateway regression guard asserts the honest three-event email flow passes under the default policy. gateway/README.md rate-limit note updated. The deeper gap (the net-state recovery probe is session-gated, so any real transport failure on the session-less login/confirm screens still cannot self-heal) is left as a known residual, deferred by the owner.	2026-07-13 22:48:59 +02:00
