Stage 17 round 6 (#13/About): About screen content + app version from git describe
- About screen: prominent localized title (Scrabble / Эрудит (Скрэббл)), a rules link
  (en/ru Wikipedia), and the Random-game / Game-with-friends sections; copy lives in a
  shared aboutContent module (the landing will reuse it). The random-game move limit
  inlines the 24h auto-match clock.
- App version: Vite define __APP_VERSION__ from VITE_APP_VERSION (default 'dev'), wired as
  a Docker build-arg sourced from `git describe --tags --always` in the deploy step — no
  manual version bumps. The fallback keeps a plain/local build working.

# Multi-stage build for the gateway service. A node stage builds the static UI
# (Vite), the result is embedded into the Go binary (gateway/internal/webui/dist),
# and the Go stage — mirroring platform/telegram/Dockerfile — yields a static
# binary shipped on distroless nonroot. So the single binary serves the SPA at /
# and /telegram/ (docs/ARCHITECTURE.md §13) with no separate static container.
#
# The production UI build vars are image build-args, baked into the bundle.
# Build from the repository root so go.work, pkg/, gateway/ and ui/ are all in the
# Docker context:
# docker build -f gateway/Dockerfile \
# --build-arg VITE_GATEWAY_URL=https://example \
# -t scrabble-gateway .
