/**
 * CommandPalette — the rendered half of the Cmd/Ctrl+K surface. Selection,
 * ranking, and grouping live in `/session-shell` (`buildCommandPaletteItems`,
 * `filterCommandPaletteItems`, `groupCommandPaletteItems`); this component is
 * the overlay, the input, and the keyboard model.
 *
 * Placement follows the PopoverSurface canon (AGENTS.md "UI chrome
 * ownership"): the panel PORTALS to `document.body` and positions in viewport
 * coordinates (`fixed`), so no host markup — a scroll rail, a `transform`, a
 * stacking context — can clip or trap it. Unlike the pickers it is CENTERED,
 * not trigger-anchored: a palette has no trigger, so it does not reuse
 * `PopoverSurface` itself, but it carries the same grammar — `bg-popover`,
 * `border-card-edge`, `OVERLAY_SHADOW`, the stamped surface attribute.
 *
 * The keyboard model is the ARIA combobox pattern: focus stays in the input,
 * ArrowUp/ArrowDown move `aria-activedescendant` across the FLAT result list
 * (groups are presentation), Enter selects, Escape closes, and closing returns
 * focus to whatever had it before the palette opened.
