/* shared-app/frame.css — the page frame factory (slice 2 of the
   2026-09-03 patch batch: docs/PATCH-NOTES-ACCOUNTS-ACCESS-UI-2026-09-03.md,
   "Owner ruling 08:00 ET: layout law for EVERY page"). Round 4's
   through-line ("round 3 fixed pages, round 4 fixes the factories" -
   docs/design/UI-ROUND4-PLAN.md) applies again here: one shared CSS
   sheet gives every page that adopts .sf-frame the same full-width
   layout, fixed chrome and non-shifting drawer, rather than a per-page
   restyle that drifts the next time someone touches one app and not
   the other two.

   TOKENS ONLY. This sheet declares no :root block and no hex literal -
   every colour, radius, spacing and font below names a token
   /dashboard/tokens.css already defines (--ink/--muted/--line/--card/
   --bg/--s1.._s5/--r/--r-cmd/--r-touch/--mono/--sans/--disp/--dur/
   --ease), the same "one token authority" contract entry-app/styles.css
   and setup-app/setup.css already keep (see each file's own header).
   Loaded by entry-app, dashboard-app and setup-app the same way
   shared-app/session-core.js is already imported by all three apps'
   api.js - here, the analogous move for a stylesheet is a <link> in
   each app's own index.html (session-core.js has no CSS of its own to
   set precedent, so this is the natural extension of "one shared
   surface, three doors").

   THE GRID. max-width 1380px + 36px gutters (14px under 767px) is not
   invented here - it is dashboard-app/ledger.css's own `.content` rule,
   read verbatim (the dashboard's grid tokens the layout law calls for).
   A page inside .sf-frame gets the SAME width discipline the dashboard
   already has, instead of a second, slightly-different full-width rule
   that could drift from it.

   NOTHING MOVES. .sf-header (and its optional .sf-filters row) are
   `position: sticky` so they hold their place while .sf-content
   scrolls under them - no eyebrow-then-h1-then-tab restatement (chrome
   law), just the one place a page states its name. The drawer
   (.sf-drawer/.sf-drawer-scrim) is `position: fixed`, exactly the
   pattern dashboard-app/ledger.css's own #drawer already uses (off-
   canvas, slid in with `transform`) - a fixed-position element is
   removed from normal flow, so opening or closing it can never change
   .sf-content's measured box. That is what "opens WITHOUT shifting the
   content" means at the CSS level, not a JS measurement trick. */
