/*
  Screen 07 — Home: Platform Shell.
  No frozen visual concept exists for this screen (SCREEN_07_HOME_PLATFORM_SHELL.md
  is behaviour-only, by its own explicit statement) — this layout is a
  narrow, minimal extension of the visual grammar already established
  across Screens 01–06, not a new register. No charts, no coloured KPI
  tiles, no icon grid, no customisable layout.

  A second, explicitly-flagged deviation from SCREEN_07_HOME_PLATFORM_SHELL.md
  (the first being the Home → Screen 06 pathway, recorded in prototype/README.md).
  The frozen specification orders Home's Information Hierarchy attention-
  first ("does anything need my attention today" as the very first thing
  answered) and explicitly forbids per-market cards on Home ("never
  expanded into per-market cards... reachable only by continuing to
  Screen 05"). A direct, explicit human instruction for this refinement
  sprint reordered the page to establish the monitored universe first —
  Hero, then Universe Summary, then Material Changes, then per-market
  cards — and required exactly the per-market card treatment the frozen
  document names and forbids. That instruction is treated the same way
  the Screen 06 deviation was: implemented as directed, and recorded here
  rather than silently reconciled with the frozen document.

  Accent: still reserved for the single active continuation in the
  Attention state only (the "present moment" the customer needs) —
  absent from the Hero, Universe Summary, and Monitored Markets cards,
  which stay in the same accent-free register Screen 05 already uses for
  its own portfolio-wide content.

/* Wider than the shared --content-max (40rem) reading-column token used

   row and Monitored Markets cards, not prose, so it reads as a workspace
   rather than a document at typical 14-16" laptop widths. 64rem centred
   is ~71% of a 1440px window and ~80% of a 1280px one — still clearly
   margined and centred, never full-width. Scoped to Screen 07 only (the
   shared token and every other screen's own .page-shell are untouched)
   and gated above the existing 900px tablet breakpoint below, so tablet
   and mobile keep exactly their prior width and behaviour. */
