zen-velixir-run

Minimal .NET 10 Blazor Server app on the velixir free tier (0.25 vCPU, 256 MB).

• Live message board: anyone posts up to 500 chars, everyone connected sees it instantly. In memory only, newest 50 kept, 2 s per-visitor cooldown.
• Header shows server time, ticking every second from one shared server timer.
• No third-party packages, CSS or JS. Evergreen browsers only.
• Component styles in *.razor.css; globals and color tokens (light-dark()) in wwwroot/app.css.
• Binds to PORT when set; honors X-Forwarded-For/X-Forwarded-Proto from the edge.
• Memory cap: workstation non-concurrent GC, ConserveMemory=7, no tiered PGO, invariant globalization, short disconnected-circuit retention, 2 unacked render batches per circuit.
• Data protection keys are in-memory; a restart invalidates antiforgery cookies, so that log category is off. Restarts show as Application started in logs.
• Messages truncate on grapheme boundaries.
• Push to main deploys via .github/workflows/velixir.yml (secret VELIXIR_API_KEY).
