Use via.OnKeyDownMap for snake keybindings, replacing the manual
dataExpr/rawDataAttr workaround. Window-scoped key handling removes
the need for tabindex/focus hacks, and WithPreventDefault on arrow
keys prevents page scrolling during gameplay.
Introduce a 60 FPS tick loop with a separate snake movement speed
(7 cells/s) so direction input is polled every frame but game state
only advances at the configured rate.
Use via's embedded NATS server to notify players of state changes
instead of a 100ms polling ticker. Each player subscribes to
"game.<id>" on page load; via auto-cleans subscriptions on disconnect,
eliminating the need for manual player tracking and RegisterSync.
Use gotailwind (standalone Tailwind v4 via Go tool) with DaisyUI
plugin files — no npm needed. CSS is compiled at build time and
embedded via a Via Plugin that serves it as a static file.
Custom "connect4" theme: light, warm, playful palette with red/yellow
accents matching game pieces and board blue accent.
