/* shared/sheet.css — the ONE bottom-sheet primitive (mobile redesign 2026).
   Every phone-width popover/menu/dropdown routes through shared/sheet.js and
   wears these `.tcg-sheet*` classes: grabber, 44px option rows, one scroll
   context, never stacked. Absorbs the look of the older section-scoped
   `.dk-sheet` / `.cl-sheet` / `.tcg-arrange-pop` patterns into one neutral
   vocabulary (the "one sheet rule"). Anatomy values are lifted verbatim from
   the mobile-redesign handoff (README §Bottom sheets + reference.html 1b frame).

   Phone-only surface. It renders at any width the JS opens it at, but the app
   only opens sheets on phone (data-platform="mobile" / < --bp-lg); desktop keeps
   its anchored popovers. --z-bottom-sheet (90) sits above the dock + tabbar and
   below the drawer/palette rungs. */
