/* ==========================================================================
   F1 Track Picker — the Lights-Out Hot Lap (Sports)
   Bespoke f1-circuit-engine.js. The five reds fill, LIGHTS OUT, a car sweeps the
   pit straight past anonymous marker boards and settles under the gantry; then
   the winning circuit's outline DRAWS ITSELF and the Grand Prix name lands.
   ⚠️ The car travels an OPEN straight line and the boards carry nothing that
   identifies a circuit, so it is not a wheel in disguise and it cannot spoil the
   answer before the winner is locked.
   ⚖️ NO logos, liveries or official track maps — each outline is an original,
   stylised hand-drawn schematic.
