Phase 0: scaffold cup26 — Vite+React+Fastify TS PWA, broadcast theme, app shell

Mirrors the TTRPG stack (strict TS, Tailwind 4, vite-plugin-pwa, esbuild server
bundle, multi-stage Dockerfile, Traefik compose). Floodlit-pitch design tokens,
UI primitives (Button/Card/Badge), TanStack Router shell with Live/Groups/
Bracket/Predict/Story routes (placeholders), dependency-free PWA icon generator.
Raw data staged: openfootball 2026 fixtures + martj42 international results CSV.
