/**
 * frontend.css — Public FileSeller frontend styles.
 *
 * Load order: [inline <style> all color tokens] → tokens.css → base.css → frontend.css
 *
 * @since 0.8.0
 * @since 0.8.0r  Redesigned: branding token overrides replace ad-hoc fs-* approach.
 * @since 0.9.9   Mobile: .fs-article padding reduced at 760px breakpoint.
 * @since 0.10.1  .checkout-grid, .form-legal-note added for checkout form.
 * @since 0.9.5   Branding override :root block removed. All color tokens are now
 *                injected directly by frontend.php's inline <style> as pre-computed
 *                rgba() values (no color-mix, no var()-in-color-function).
 *                This file now covers only frontend-specific component additions.
 *
 * base.css and tokens.css already provide the full component library:
 *   .page-shell, .site-header, .brand, .main-nav, .header-actions,
 *   .hero, .hero__grid, .panel, .hero__content, .hero__eyebrow, .hero__visual,
 *   .section, .section__header, .kpi-grid, .feature-grid, .product-grid,
 *   .process-grid, .card, .badge, .cta-banner, .site-footer, .footer-grid,
 *   .footer-bottom, .mock-window, .mock-card, .list, .list-item,
 *   .btn, .btn--primary, .btn--ghost, and responsive breakpoints.
 *
 * No backend CSS leaks into this file or into the frontend layout.
 * The only shared component is views/partials/platform-signature.php.

   Support-Seite Hero Visual Slots (@since 0.13.96, updated 0.13.97, 0.13.98)

   Three configurable slots (S1 left large, S2/S3 right stacked) inside the
   hero__visual mock-window on the support page.

   Image slot (.fs-support-slot__img):
     Fills the parent mock-grid cell with object-fit: cover.

   Text slot (.fs-support-slot__text + .meta-card):
     Uses .meta-card for typography (strong/span) — fully Design-System-aware,
     all sizes via rem/CSS variables. No hardcoded font sizes.
     S1 uses flex column + space-between: the 3 content blocks (.fs-support-slot__block)
     distribute adaptively to fill the full slot height. Spacing between blocks
     expands/contracts depending on available vertical space.

   Block wrapper (.fs-support-slot__block):
     One wrapper per Überschrift+Freitext pair in S1. Acts as a flex item inside
     .fs-support-slot__text. Only rendered when the block has content.

   Fallback icon (.fs-support-slot__icon-fallback):
     Shown in S2 when no image and no text configured. Inline SVG headset icon,
     coloured via var(--accent). Hidden if user provides image or text.

   Empty slot (.fs-support-slot__empty):
     Renders .card border / background with no content — used by S1/S3 when empty.

   Mobile Slot-Stack (.fs-support-slot-stack):
     Hidden on desktop; shown on mobile when NOT all 3 slots carry images.

   rich_text-Block — Quill WYSIWYG Frontend-Ausgabe
   @since 0.18.96
   @since 0.18.97  Abstand-Fix (fs-rich-text__panel), Farb-Fix h1-h6,
                   first-child margin-top-Reset.
   @since 0.18.98  Abstand zwischen Überschrift und erstem Absatz reduziert:
                   h1-h6: margin-bottom: 0.5em (Browser-Default ~0.83em → kleiner).
                   Leere Quill-Absätze <p><br></p> werden kollabiert
                   (margin: 0; line-height: 0; height: 0; overflow: hidden).

   Die section.hero-Wrapper-Klasse bringt aus base.css folgende
   Regeln mit, die für rich_text-Inhalte unerwünscht sind:
     .hero p { color: var(--text-soft); max-width: 62ch; margin: 18px 0 0; }
     .hero__content { padding: 36px }  → zu großer oberer Abstand vor Überschriften

   Korrekturen für .fs-rich-text (Farbe, Breite, Abstände):
     - p: color: var(--text)   → Basis-Fließtextfarbe (Inline-Farben per Spezifität drüber)
     - p: max-width: none      → volle Panel-Breite
     - p: margin: 0 0 1em      → konsistenter Absatzabstand
     - h1-h6: color: var(--text) + max-width: none (übersteuert Basis-Regeln)
     - h1-h6: margin-bottom: 0.5em → Abstand nach Überschrift kompakt (@since 0.18.98)
     - > *:first-child: margin-top: 0 → kein Extra-Abstand vor dem ersten Element

   Korrekturen für .fs-rich-text__panel (Panel-Padding):
     - padding-top: 20px statt 36px → Überschrift näher am oberen Rand (@since 0.18.97)
