/* AgentOS — the visual second brain.
 *
 * One committed world: a mission-control instrument panel. Not a SaaS dashboard,
 * not a note-taking app. The vault is telemetry from a running system, so data is
 * monospaced and tabular, chrome is quiet, and the map is the only thing allowed
 * to glow.
 *
 * Rules this file holds itself to:
 *  - Body and secondary text clear 4.5:1 on the panel background. The previous
 *    --dimmer (#4c5567) was 2.9:1 and shipped as real label text; it is gone.
 *  - Shadows carry an offset and a soft blur. No zero-offset coloured halos.
 *  - Backdrop blur appears only where a panel sits over the live canvas, which is
 *    a specific effect. It is not decoration sprinkled on opaque surfaces.
 *  - One authored motion moment: surfaces arrive on an exponential ease-out, and
 *    the map drifts. Everything else is a 120ms state change.
 *  - The surfaces the browser owns are themed: selection, caret, scrollbars,
 *    focus rings, placeholders, underline offset, tabular numerals, accent-color.
 *  - No gradient text, no eyebrow labels above headings, no 01/02 section
 *    numbers, no emoji standing in for icons, no monospace as costume.
