Fix the format gate and the Cyber Context styling, and pin the redesign

CI failed at format:check: the format scope still listed the deleted
panelChrome.radioOwnership test, and panelRails.test.mjs needed Prettier
after its glow list shrank.

The new Context title colour outranked Cyber's red panel titles, and the
collapsed Context launcher came out brighter than its siblings; the rule
now applies only to the expanded panel outside Cyber. Cyber's layout-focus
standby card had relied on the old dashed border and centring, so it
drew a 3px frame with its text off the radar art; it now names its own
1px frame, padding and centring. Cyber also drops the shared segmented
track, which drew a third frame around its already framed mode buttons.

Tests now pin the Context header to its title and collapse control, the
segmented control, 10px type, the missing halo and the scoped title
colour, plus the Cyber standby and track overrides. Each fails on the
previous CSS or markup.

qa-radio enables Radio and starts the first Play from the visible
controls, expanding Context and Radio the way a person must, then puts
the panels back. The Escape test and its mutation describe what they
still protect. CURRENT-STATE no longer describes the removed Radio icon
or compact player.
