Editorial pricing tiers that adapt to the site theme: section > container > header (eyebrow, h2, intro) > a row of "Adaptive Tier" component instances, each with an optional glyph, plan name, badge, tagline, price (currency, amount, period), description, up to six features, CTA and note. Every line and muted colour is mixed from currentColor, so one set of rules reads correctly on light, dark and auto themes; the featured tier inverts against the page. Tier props: glyph (none|spark|stack|orbit), name, headingLevel, tagline, currency, price, period, description, feature1-6 (empty hides the row), featured, badge + showBadge + badgeTone (accent|ink|outline) + showBadgeDot, ctaLabel, ctaUrl, ctaStyle (solid|outline|link), note + showNote, showDescription, showCta. Section options (data attributes): data-theme (light|dark|auto) on the section; auto follows the visitor's prefers-color-scheme; data-accent (primary|secondary|accent|neutral) picks which ACSS colour drives badges, checks and CTAs; data-surface (joined|separate|elevated|outline) joined draws every tier inside one hairline frame, the others split them into cards; data-radius (none|s|m|l|xl) outer corner radius; data-columns (auto|2|3|4) tiers per row on wide containers (auto fits by width); data-align (start|center) header alignment; data-density (compact|comfortable|airy) inner tier spacing; data-anim (rise|fade|none), data-duration (ms), data-stagger (ms), data-once (true|false) entrance motion when the row scrolls into view. Keyboard focus rings on every CTA, AA contrast in all themes, reduced motion shows tiers instantly, works without JS.
