- 'Star it on GitHub' links in the race menu, help panel and final
classification (the app had no link to its source)
- LICENSE: the README said MIT but the repo had no license file, so GitHub
showed it as unlicensed
- README call to action in both READMEs

Make the app work on phones: collapsing standings, bottom-sheet what-if, touch
On screens narrower than 760 px (or shorter than 500 px, i.e. phones in
landscape):
- standings collapse to position + name; a "Standings" pill expands every
column (tyres, laps, gaps) as an overlay
- the what-if panel becomes a bottom sheet with a close button
- toolbar, speeds and timeline stack at the bottom; the minimap, tyre
legend and fastest-lap badge are hidden; header and menu scale down
Touch input on every screen: the timeline drags with pointer events (with a
larger grab area), and a two-finger pinch zooms the track.

Ghost car takes the pit lane at its own stop, not the real one
Each what-if lap now replays a real lap of the right kind, re-timed to the
what-if lap time: normal laps copy the driver's nearest normal lap, and the
what-if in-lap and out-lap copy a real pit stop (the driver's nearest one,
else another driver's). The label shows PIT while the ghost is in the pit
lane. Previously the ghost followed the real car's path, so it skipped its
own stop and went through the pit lane at the real one.

Add the pit-stop what-if, a race switcher and shareable links
- Pit-stop what-if: follow a driver, press W, choose "pit at the end of
lap N for <compound>" or "stay out". The server simulates 10 laps with
the real strategy and with the alternative, and the panel shows the
projected position, the gap to each nearby rival, a calibrated chance
of being ahead, and what really happened; "Watch it" replays the
alternative as a ghost car.
- ml/: lap-time model (gradient boosting on every green-flag lap since
2023), lap-by-lap race simulator, backtests and calibration. On 30
unseen races the model beats "pace stays the same" in 27; on 451 real
pit stops it predicts the gap 10 laps later with 6.4 s error vs 8.8 s
for "gaps hold + pit loss" (Brier 0.059 vs 0.070). Full-race order
prediction does not beat the baselines yet, so the what-if looks 10
laps ahead.
- The Docker build trains the model from ml/laps_train.csv; race JSON
now embeds a per-lap table (shared lap_rows() in fetch_data.py).

Add team radio, built-in showcase races and traced pit lanes
- Team radio: the replay plays each driver's real radio clip when the
race reaches it, with a pulsing ring on the car and a log entry. Plays
at 1x and 5x; while following a driver only their radio plays; R key
and a Radio button toggle it.
- precache.py downloads five showcase races into race_seed/ at Docker
build time so they load instantly; race data is served gzipped.
- Pit lanes are traced from a timed stop in the same session instead of
track_layouts.json, where 14 of 24 pit lanes jump across the circuit.
- Cache folders are writable by the Hugging Face runtime user (uid 1000);
backslashes are stripped from race file names.
- README: full version moves to .github/README.md (shown on GitHub); the
root README keeps the Hugging Face Space config.
- ml/: lap dataset builder and lap-time model script for the upcoming
strategy simulator (model evaluation still to run).

F1's live-timing archive that FastF1 reads (livetiming.formula1.com/static)
now answers every request with 401 Unauthorized, so sessions loaded with no
laps or telemetry and no race could be downloaded.
- fetch_data.py: fetch positions, laps, stints, pit stops and race control
from the OpenF1 REST API (2023 onwards), keeping the same output JSON.
Race distance comes from snapping positions onto the circuit outline;
layouts that don't match the session's coordinates fall back to an
outline built from the session's fastest lap. Raise on failure instead
of returning silently.
- serve.py: schedule from OpenF1, redirect / to the simulator, report an
error when nothing was exported, ASCII startup message.
- simulator.html: years from 2023, show HTTP errors on data loads.
- Fix the prebuilt-layout lookup (it looked in race_cache/), the README
clone URL and port, and drop the fastf1 and requests-cache dependencies.
