/* ── ODIV Inbox — BASE / LAYOUT LAYER ───────────────────────────────────────
   Uses design tokens from /css/variables.css.
   Safe-area insets for iOS notch + home indicator.

   ⚠️  This is the FOUNDATIONAL layout layer for the v2 PWA. It declares the
   structural properties (position, display, flex, overflow, …) that the
   v2 polish layer (/inbox/v2/css/inbox-v2.css) builds on top of. Both
   files load on /inbox/v2/index.html in this order: v1 first, v2 second.

   Editing rules (#193, post-mortem 2026-04-17):
     - DO NOT delete a structural rule here without first checking that
       v2 either redeclares it OR doesn't depend on it. The bug pattern
       that bit us was the OPPOSITE direction: v2 declared a partial
       override that silently inherited a stale v1 structural property.
       But removing v1 rules cold has the same risk.
     - For new component styling, ADD to inbox-v2.css instead. v1 should
       only change to fix bugs in load-bearing layout.

   The future Vite migration (#194) will collapse this file into the v2
   source tree — until then, treat both files as one logical stylesheet
   split across two physical paths.
