F1 live timing graphics, driven by Rive data binding

The Formula 1 half of my FLAGFALL broadcast package: lap gaps, a DRS band, lead markers and a lap-time trace, all rendered as Rive graphics. JavaScript writes the bound properties frame by frame while the run plays. The run shown is a replay reconstructed from OpenF1 lap timing rather than a live broadcast feed, and the graphic says so on screen. The same .riv re-captions its modules from whatever data it is given, so one file serves two sports.

Built for the Rive Broadcast and Livestream UI Challenge. The moment banner, autoranging lap-time trace and module captions are all data-bound text and number properties rather than baked timelines: the runtime writes roughly 245 bound properties per frame into the file while it runs.

Part of the FLAGFALL build, published separately because it is a distinct deliverable: the same instruments that carry a chess broadcast re-skin themselves into a race timing screen with only the adapter changed.
