feat(banner): per-campaign colour overrides and urgent alerts
Non-default campaigns gain an optional colour override (background / text /
link) in two sets — one for every theme, one for the dark theme only — and an
"urgent" flag.

- Colours ride profile.get as six trailing FlatBuffers strings on
  BannerCampaign (backward-compatible). The client resolves the cascade
  (dark <- dark ?? all, light <- all) per rendered theme and derives the strip
  border from the background in JS (no CSS color-mix, for the old Android
  WebView floor); AdBanner applies them as inline vars scoped to the strip.
- Urgent is resolved entirely server-side: while any enabled, in-window urgent
  campaign exists, computeActiveSet returns only the urgent campaigns and
  bannerFor skips the eligibility gate — so a system notice reaches every viewer
  (paid / hint-holding / no_banner included) and preempts the ordinary feed. No
  wire field; it appears on each viewer's next profile.get.
- Admin console (/_gm/banners): native colour pickers + a live light/dark
  preview of the strip, and an urgent toggle. The default campaign stays plain,
  enforced by the service and a DB CHECK.

Migration 00009 is additive (nullable colour columns + a bool default +
all-or-nothing / hex / default-plain CHECKs) — expand-contract, rollback-safe.

Docs: ARCHITECTURE §10, UI_DESIGN, FUNCTIONAL (+ru). Tests: ads unit (urgent
preempt + colour validation), codec + resolver unit, gateway transcode, and
integration (colour round-trip + urgent bypass against real Postgres).

pkg

Shared wire contracts for the Scrabble platform (module scrabble/pkg), imported by both backend and gateway. It carries no logic — only the generated message types and the schemas they come from.

Layout

proto/push/v1/    # backend -> gateway live-event gRPC channel (Push.Subscribe)
                  #   committed generated Go (*.pb.go, *_grpc.pb.go)
fbs/scrabble.fbs  # FlatBuffers edge payloads (one `scrabblefb` namespace)
fbs/scrabblefb/   # committed generated Go for the schema
  • proto/push/v1 is the single gRPC server-stream the backend exposes and the gateway subscribes to (Event{user_id, kind, payload, event_id}); the payload is an opaque FlatBuffers body the gateway forwards verbatim.
  • proto/telegram/v1 is the Telegram connector's RPC contract (including ValidateLoginWidget for the web Login Widget sign-in).
  • fbs holds the client↔gateway request/response and event payloads as FlatBuffers tables. The backend encodes the push payloads from these types; the gateway transcodes the rest to and from the backend's JSON; the UI generates TypeScript from the same .fbs.

Generated code

Committed (CI only builds it); regenerate dev-time after editing the schemas:

make -C pkg tools   # go install protoc-gen-go + protoc-gen-go-grpc
make -C pkg gen     # buf generate (proto) + flatc (fbs)

flatc is pinned to 23.5.26 to match the github.com/google/flatbuffers Go runtime in go.mod; generating with another version is refused.

Workspace wiring

scrabble/pkg is a bare-path module (no dot), so — like scrabble-solver — it cannot be fetched as a versioned dependency. go.work carries use ./pkg and replace scrabble/pkg v0.0.0 => ./pkg; consumers require scrabble/pkg v0.0.0.
