/* =====================================================================
   CoreCraftia - windows.css (Phase 2)
   Layout layer for every window / modal / full-screen scene that sits on
   top of the game: auth, lobby, profile+inventory, adventure journal,
   skills, shop, friends, menu, settings and the small dialogs.

   Rules of this file (same architecture as hud.css):
   - one shell contract for every window: a fixed overlay that pads by the
     safe area, and a panel that never exceeds it and scrolls INSIDE
   - sizes come from tokens + fluid clamps, never from the resolution
   - two width breakpoints (compact <1024, phone <640) plus one height
     modifier (short <480px landscape); no zoom/scale, no JS coordinates
   - cosmetics (colors, borders, fonts) stay in corecraftia-ui.css - this
     file only owns geometry and flow.
   ===================================================================== */
