▸ what the chat client, control center, and hub look like at phone widths
⚠ DESIGN-TIME MOCK
These are visual mockups. The desktop pages (app.html, chat.html) currently render fixed-size — a real mobile build would tap the same APIs (/health, /gpu, /chat) but lean on a bottom tab bar instead of the sidebar, and use Discord's existing app for the actual chat surface. Use this as the design target if you want to bundle a companion PWA.
