/*
 * pricing.css — page-scoped styles for the marketing pricing page (/{locale}/pricing).
 * Loaded ONLY on that page (via the pricing view's @section('styles')), after marketing.css, so it
 * reuses the shared :root tokens (--bg, --text, --muted, --border, --green, --green-hover, --accent,
 * --hero-bg, --sky-*, --focus) and only adds pricing layout. The site is dark-only; this page is the
 * 'night' theme (no .blog-body light scope). Kept out of marketing.css so the home/critical path
 * isn't burdened with styles only /pricing needs. No JavaScript — the page stays byte-identical /
 * CDN-cacheable. The page prices the prepaid-credit model: three per-minute rate cards (the price
 * shown is the per-minute rate), a metering explainer, and the bring-your-own security note.
