/* ============================================================
 * imjustdex.com — phase0.css
 * Ministry Marketing OS — Phase 0 landing page.
 *
 * This stylesheet is scoped to the /phase0/ route. It relies on
 * tokens.css for the design system and shell.css for the site
 * chrome (masthead, brand block, mode toggle, rulers, footer
 * strip, skip link, sr-only). Every declaration below is unique
 * to the phase0 page — any rule that would duplicate tokens.css
 * or shell.css has been deleted.
 *
 * Load order: tokens.css → shell.css → phase0.css
 * No inline styles. No inline scripts. Strict-CSP compliant.
 *
 * Doctrine:
 *   • Color tokens come from tokens.css (--bg, --ink, --panel,
 *     --border, --rule, --accent, --accent-text, --body-color,
 *     --body-muted, --body-tint). Never hard-code.
 *   • Typography: --display / --body / --mono, paired with
 *     --size-*, --text-*, --lh-*, --track-*.
 *   • Spacing: --space-* scale only.
 *   • Motion: --motion-* + --ease-default.
 *   • Dark mode: handled by tokens.css via html.dark-mode; this
 *     file never references html[data-theme], html.dark-mode, or
 *     @media (prefers-color-scheme). Tokens flip themselves.
