/* app.css — webapp Surface 2 (mobile-first /app/* shell + page primitives).
   Plan 04-07 Task 1: fills the empty stub created in 04-03. Per BLOCKER 2 fix
   App.razor's <link> tag is already in place — this plan only fills CSS content.

   Tokens (--color-*, --font-*, --radius-*) come from default.css.
   Per CONTEXT D-18..D-21:
     - Mobile-first 480/640px shell (no desktop sidebar — phone-shaped surface).
     - Status badges follow Aquatic tokens (uploading/processing/done).
     - Polling lifecycle owned by SessionDetail.razor + WebappStatusPoller.

   Surface composition mirrors sketch-findings-arapaima/references/surfaces.md
   "Surface 2 — webapp shell, mobile-first capture flow". */
