/*
 * home-builders.css — the three homepage builder panels, redesigned.
 *
 * Each panel is its own instrument rather than a shared card:
 *   · Automations (#dp-au-inline) — an amber operations console: job-ticket
 *     input, platform keys with LEDs, a physical RUN key, and a live pipeline
 *     board that mirrors the /automation canvas (dotted grid, flowing wires).
 *   · AI Agents (#dp-ag-inline) — mission control: a HUD-braced brief, shape
 *     cards with node-graph glyphs, and a dark sandbox viewport where the
 *     team orbits its lead (deliberately dark in both themes, like a monitor).
 *   · Skill.md (#dp-sk-inline) — the document itself: an editor window with a
 *     SKILL.md tab, line-number gutter, live frontmatter, and the textarea
 *     embedded as the body of the file.
 *
 * Built entirely on tokens.css (--surface/--fg/--border/--shadow/--s-*) so
 * light + dark both come for free. Per-builder hues stay the deliberate
 * identities: amber / indigo→cyan / violet.
 *
 * JS contract preserved: panel ids, .au-pf pickers (aria-pressed), #ag-build /
 * #sk-build, .hb-result hosts, .hb-cost pills. Loaded by index.html only.
 *
 * NOTE: animations here play regardless of prefers-reduced-motion — site-wide
 * product decision (2026-07-11); do not add reduce guards.
