/* niki-bar.css — universal Niki command bar (Day 10h).
 *
 * Floating overlay + card matching the report.html / dental-uiux.html
 * brand bar: Inter + Space Grotesk, accent halo, gradient mic glow,
 * accent-tinted Niki bubbles. All surfaces use the existing CSS variables
 * from base.css so dark / light / high-contrast all inherit for free.
 *
 * Layout:
 *   .niki-bar-overlay  — fixed full-screen backdrop (display:none by default)
 *   .niki-bar-card     — 600px-wide command card, top 14vh
 *
 * Open animation:
 *   backdrop fades in 200ms, card slides down + fades.
