/* ============================================================================
   AgudaOS · os.css — chrome, desktop, dock, panels, lock, phone (BRAND.md "Pulse"; tokens in os/tokens.css).

   RTL chrome decision (AgudaOS · BRAND.md §10.1). The OS is Hebrew-first, so "start" = right.
   - Menu bar: RIGHT (start) = system: AgudaOS mark, then the active app and its menus.
     LEFT (end) = status: tenant badge, desk switcher, search, control centre, notifications, date + time.
   - Window title bar: app tile, poster title and record crumb at the RIGHT. Caption buttons at the LEFT edge, like Windows
     in Hebrew: from the left edge close · maximize/restore · minimize (DOM order min, max, close as the last flex children).
   - Banners, notification centre and control centre open from the LEFT (the status side).
   - Snap layouts are mirrored: wide/tall zones on the right, zones numbered right to left.
   - Phone: back button at the right with a right-pointing arrow; back swipe from the right edge.

   Blur budget (BRAND §5.3): menu bar, dock and ONE focused surface (search OR control centre OR notification centre).
   Windows, flyouts, menus and widgets are always solid. Only transform/opacity animate.
   Everything classic (views inside windows, dialogs, toasts) is re-coloured by os/bridge.css.
