   ATLAS V6 — TODAY COMMAND SURFACE · enterprise polish T2b  (css/v6-t2b-today.css)
   ────────────────────────────────────────────────────────────────────────────
   Surface : #v6-today (data-view="home") — the executive home page only.
   Dated   : 2026-06-29 · LOADS LAST, immediately before css/v6-lock.css.
   Fixes Codex findings F1 (floating cards over a dead cream band) + F7 (three
   dark panels compete). Sibling sheet css/v6-t2-today.css owns the Decision-Queue
   grid + empty-state craft; this sheet ONLY adds the full-height composition and
   the dark-panel hierarchy. No markup/JS/voice-id changes. One gold accent, zero
   cyan/teal. No body scroll — internal panel bodies absorb overflow.

   F1 — WHY the dead band exists (verified in the live DOM):
     .canvas#main-content is `flex:1; display:flex; flex-direction:column`
     (bundle-base.css) and the voice dock (#hint-bar.quick-bar, flex-shrink:0)
     is an in-flow sibling BELOW it inside .main-col — so the canvas already
     reserves the dock's height. #view-home is `display:contents` (training.css),
     so #v6-today is effectively a direct flex CHILD of .canvas. But base
     v6-today.css sets `#v6-today{display:block}` with no flex-grow, so it sizes
     to content (~787px) inside a ~920px work area → a dead band below it, and the
     grid (sized to its tallest column) never reaches the work-area floor.
     Fix: make #v6-today fill the canvas, make the grid fill #v6-today (minus the
     preserved page header), and let each column's TERMINAL card consume the slack
     with an intentional internal layout. Stretching never increases the tallest
     column, so the 1920×1080 no-scroll frame holds.

   Scope guard: the height-fill block is gated to `min-width:1281px` — the same
     breakpoint where the base 3-column single-row layout applies (base switches
     to 2-col at max-width:1280px). Below that, tablet/mobile stacking + scroll is
     left untouched (no forced fill that would squish the stacked layout).
