/* LLMQA dashboard — "newspaper / lab-notebook" theme (light + dark).
 *
 * Design rules:
 *  - Ink-on-paper: dark text on light, hairline rules, generous whitespace.
 *  - Newspaper hierarchy: serif display headings, small-caps section labels.
 *  - Lab notebook: monospace for ALL data (ids, scores, costs, timestamps).
 *  - Color is reserved strictly for TEST STATE and appears ONLY in the
 *    per-case results table. Summary cards and the trend chart stay pure ink.
 *  - Accessibility: state is never color-alone — always color + glyph + label,
 *    and the shades are contrast-safe / WCAG-AA on their background.
 *
 * Theming: everything reads from the tokens below, so light and dark are a
 * single palette swap. The dark palette keeps the same warm-newsprint feel
 * (a night edition on toned paper), not a cold blue-gray. Filled controls read
 * from --on-ink / --ink-strong so "ink" backgrounds invert cleanly.
