Stacked on #326: a change to the readout column asked for after demonstrating the control panel to a stakeholder.

The problem

In use, the frequency at the cursor is by far the most important number in the panel. It was already large, but time was set directly above it at the same size and with the same bloom, so the two competed for the eye and neither was the first read.

The change

• Frequency is now the only large (36px), lit reading, at the top of the column under the kicker.
• Time sits immediately beneath it at 19px, captioned TIME, in the same grey as the panel's labels (--gf-muted) rather than in ink, with no bloom.
• Doppler at the foot takes that same second rank (19px, label grey). It was 19px in ink; two secondary rows at one size in two colours would have read as a third rank, so it follows time. One line to revert if the white was wanted.
• The hairline that separated the two large readings goes with the second large reading.

Nothing else moves. The LEDs keep their accessible names and classes, so every locator and the helper's getLEDValue are unchanged; docs/Control-Panel.md §3 and the CLAUDE.md entry are updated.

Checks

• yarn typecheck, yarn lint, yarn hygiene — clean
• tests/style-panel, control-row, analysis-mode, selection-highlight, player-transport — 47 passed
• yarn test:unit — 294 passed, 4 failed in multi-tab-merge.test.js. Those fail identically on the base branch without this change: the fixtures' clock is unpinned, and main already carries the fix (Grey-shades colour map: a live toggle on the player bar and a colour-map config row #333). They will clear when Rebuild the control panel to the design handoff #326 takes main.

CI: the "Hygiene, lint, typecheck, unit tests, build" check failed on 696ce65 on four cases in tests/unit/multi-tab-merge.test.js. That is not this PR's change: the same four fail on the base branch (claude/control-design-implementation-9a2bt9) untouched, because the fixtures leave now to the wall clock while asserting on tombstones dated 2026-09-05, which fell outside the seven-day TTL on 2026-09-12. Main already carries the fix (9147c49, #333). 032b2bb ports that one-file test change verbatim; locally the lane is 298/298 with lint, typecheck and hygiene clean. It no-ops once #326 takes main.
