/* ─────────────────────────────────────────────────────────────────────────
 * dockersnap docs — design overrides
 *
 * Ports the dashboard's "amber CRT meets Linear" language onto MkDocs
 * Material. See docs/DASHBOARD-DESIGN.md §3b for the source of truth on
 * tokens, palette rationale, and visual rules.
 *
 * Hard rules (carried over from the dashboard):
 *   - Sharp corners (≤ 2px). No rounded-xl, no pill buttons.
 *   - Single amber accent on interactive elements only — never on chrome.
 *   - Status colors (sage, slate-blue, terracotta) live on their own
 *     conceptual territory; admonitions get coloured left borders, not
 *     filled backgrounds that compete with the page.
 *   - Identifiers, command samples, and table numerics in JetBrains Mono.
 *   - Density over whitespace: tight tables, single-pixel borders.
 *   - Flat surfaces; no gradients, no atmospheric textures.
 * ───────────────────────────────────────────────────────────────────────── */
