The tyre deg panel expanded by default during races and rendered a
placeholder row per driver until enough clean laps existed to fit a
degradation model. For the first third of a race that was ~525px of
'warming up' rows above the Timing Tower, pushing the tower — the thing
the page exists for — off the fold entirely.
The panel now opens when it has something to say rather than because the
session is a race, and says 'collecting clean laps' while it waits. A
reader who toggles it keeps their choice.
Also:
- Hoist degradationModel into a memo shared by the readiness check and the
rows. It is O(laps) per driver and previously re-ran on every render at
feed rate.
- Order the side rail most-synthesized to most-raw, so a reader arriving
mid-session gets 'what just happened' before the regulatory log.
- Fade the trailing edge of the nav below 560px. It scrolls with a hidden
scrollbar, so the cut-off item read as a clipping bug rather than as
scrollable.
