/*
 * jarvis app.css — the browser app's own rules on top of the kit's theme.css
 * (go/rogr-kit/web/theme.css). Two parts:
 *   - the login and passkeys pages: the kit's layout as in vitals (.app-width);
 *   - the HUD (design round 3. 11. 2026, his pick „B HUD"): the visor — deep
 *     blue-black ink with faint scanlines and a soft ROGR-blue glow, corner
 *     brackets, telemetry in the corners, a curved horizon, the voice
 *     waveform, his question small and grey, Jarvis's answer large, result
 *     panels with clipped corners and the glowing talk button. Fully custom,
 *     always dark (no colour-mode switch on the visor), the kit's Open Sans.
 * No inline styles anywhere: the pages run under style-src 'self'; hud.js
 * only sets custom properties (--level, --i) through the CSSOM.
