/* AIronClaw brand override — applied AFTER Source's screen.css.
 *
 * The body is wrapped in .ac-site (see default.hbs) so this stylesheet
 * mirrors frontend/src/app/globals.css's .ac-site scope verbatim for the
 * pieces a blog needs (palette tokens, container, nav, buttons, eyebrow,
 * footer, responsive nav). Marketing-only sections (HERO art, GATEWAY,
 * PRICING, FAQ, SECURITY, SCROLLY) are deliberately omitted.
 *
 * Source-side knobs to set in Ghost admin → Settings → Design:
 *   - Brand → Accent color           : #bae95c
 *   - Site → Site background color   : #f5efe6 (default of this theme)
 *   - Site → Title font              : Modern sans-serif
 *   - Site → Body font               : Modern sans-serif
 *   - Site → Header style            : Off (the AIronClaw navbar replaces it)
