/* kiaribot.com — "Night Session" (October 2026).
   Living Octane/Fennec art, a live telemetry HUD, the measured climb against Nexto.
   One stylesheet. No style attributes anywhere: the CSP forbids them, so every
   server-rendered geometry is an SVG attribute and every script writes the CSSOM.
   Never put backdrop-filter over a canvas, and animate overlays with transform only. */
