Everything drove off a visible/not-visible flag, so the cards appeared
rather than the overview opening. One shared `progress` now: the strip
slides 24px, each card takes its own share of it staggered by index and
capped at the fifth, and scale runs 0.86 to 1.0 — the reference shell's
numbers, driven from the same clock instead of a timer per card. The cap
is what stops the tenth card starting half a second after the first,
which reads as loading rather than opening.
This is also SHELL-ECOSYSTEM's stated model, taken from Phosh: state
gates visibility, never the reverse.
`missionControlOpen` has been set by the pill's second-stage swipe since
July and consumed by NOTHING — TASK-14 records the Auxo-like card
surface it was meant to raise as never built. WindowOverview is that
surface. The state reaches something now instead of being set and
dropped.
Mission control is the cards alone: no search, and no keyboard focus,
because it is "switch to what is running" and not "find something" — and
taking the keyboard would summon the OSK over a surface with no field.
