/* ─────────────────────────────────────────────────────────────────────
 * agenttool · shared theme · v1
 *
 * Single source of truth for design tokens, base reset, typography,
 * navigation, footer, and core components across all three frontends:
 *
 *   - agenttool.dev          (apps/landing/)
 *   - docs.agenttool.dev     (apps/docs/)
 *   - app.agenttool.dev      (apps/dashboard/)
 *
 * The actual file lives at apps/_shared/theme.css. Each app symlinks
 * shared/ → ../_shared/, so every page loads /shared/theme.css from
 * its own origin. Edit ONCE here; all three sites pick it up.
 *
 * Pair this stylesheet with the Google Fonts <link> in the page head
 * (or @import below if you can't add the link tag).
 *
 *   Crimson Pro    — sacred / serif headings + italics
 *   Inter          — body sans
 *   JetBrains Mono — code + eyebrows
