/* ================================================================
   Resayil — Raven WhatsApp sidebar entry + iframe panel overlay
   Phase 24.8, Plan 24.8-04
   ----------------------------------------------------------------
   Scope: Raven routes ONLY (3 route_prefixes — see overlays/raven.json):
     body[data-route^="raven"]
     body[data-route^="/raven"]
     body[data-route*="raven-"]

   Consumes --rs-* tokens from resayil-brand.css. No new custom props.
   Class prefix: .rs-raven-whatsapp-* (distinct from Phase 24.2-04's
   .rs-whatsapp-* classes on rs-desk-whatsapp.css — zero collision).

   DOM built by rs-raven-whatsapp-channel.js (Task 1) via safe
   createElement. No innerHTML/outerHTML usage; this CSS styles the
   produced tree only.

   Depends on: resayil-brand.css (tokens), rs-raven.css (app chrome
   baseline), tabler-sprite.svg (Phase 24-01, for the brand-whatsapp
   icon rendered inside the entry).

   Coexistence: the Phase 24.2-04 global /app/* dock (rs-whatsapp-*)
   remains unaffected — it styles a separate DOM tree mounted at
   document.body. This file adds a secondary affordance inside the
   Raven sidebar; both render the same iframe contents.
