/*
 * SEO landing page styles. Explicit hex values from .interface-design/system.md.
 * No DaisyUI semantic utilities. Critical above-the-fold subset is inlined via
 * templates/seo/_critical_css.html; this file loads async and carries the rest.
 *
 * Aesthetic: warm editorial advisor. White cards floating on #FAFAF9, one indigo
 * accent (#422AD5), Figtree throughout, semantic labels as page-kind markers,
 * disclosure FAQ, arrow-led related list.
 *
 * Width system:
 *   Card column (hero, advisor, FAQ, footer, related)  ->  max 880px
 *   Prose column (.seo-article body)                   ->  max 720px  (~65ch)
 * The narrower prose column inside the wider card column creates a subtle
 * editorial rhythm — full-width "chrome", narrow reading measure.
