 * IRON LAW · NO PAGE SCROLL (1440x900)
 *
 * The viewport is locked at 100vh. The body NEVER scrolls. The
 * browser window NEVER shows a vertical scrollbar. Every page
 * that has list data (commission ledger, audit log, chat thread,
 * call history, notifications, etc.) wraps its rows in an inner
 * container with `flex: 1; min-height: 0; overflow-y: auto` so
 * the LIST scrolls internally and the page chrome stays fixed.
 *
 * See docs/IRON-LAW-NO-SCROLL.md for the full pattern + list of
 * surfaces that ALWAYS scroll internally.
 *
 * Layout chain:
 *   body  -> flex column, 100vh, overflow hidden
 *   header#apex-topbar -> flex-shrink: 0
 *   main#app-root      -> flex: 1, min-height: 0, overflow hidden
 *   .app-frame         -> flex: 1, min-height: 0, overflow hidden
 *
 * If you find yourself adding `overflow: visible` or `min-height:
 * 100vh` to any of these, STOP. Wrap the list in an internal-
 * scroll container instead.

 * CANONICAL 1440x900 FRAME-WRAP  (James-demo CRM design stage)
 *
 * Every screen in the F1 -> F10 client journey is authored against
 * a fixed 1440x900 design lock. `.frame-wrap` centers that stage
 * inside the locked viewport so the composition lays out against
 * the exact dimensions it was drawn at, with zero scroll and zero
 * reflow. On a 1440x900-or-larger window the frame fills the
 * viewport. On a smaller window the frame keeps its intrinsic
 * 1440x900 size and is letterboxed against --bg-warm so nothing
 * collapses. Internal lists still scroll via their own
 * `flex:1; min-height:0; overflow:auto` containers (see IRON LAW
 * above); the frame itself NEVER scrolls.
 *
 * Owned here as the single source of truth. The topbar / orb /
 * context-bar primitives (02) and the stage grids (03) all assume
 * this parent. Other terminals treat it READ-ONLY.
