/* ============================================
   HOMEPAGE FEATURE 3 — Guest Media Upload
   Modular CSS for the dynamically-injected upload feature.
   Mobile-first with full-screen modal and animated success.

   ARCHITECTURE:
   - Uses design tokens (CSS custom properties) from homepage.css
   - Mobile-first: stacked banner → inline banner (768px+)
   - Modal: centered panel on desktop, bottom-sheet on mobile
   - SVG circular progress ring per file upload
   - SVG success animation with staggered keyframes
   - prefers-reduced-motion respected

   DEPENDENCIES:
   - CSS custom properties from homepage.css (:root variables)
   - Font Awesome (icons via homepage.html)

   AI-OPTIMIZED:
   - Flat selectors, no nesting beyond 2 levels
   - Shared design token usage — zero hardcoded color values
   - Clear section comments for each component
   - Prefixed with "media-" to avoid class collisions
   ============================================ */
