/* ══════════════════════════════════════════════════════════════════════
   FileDrop — WooCommerce File Uploader (Frontend)

   Styles the drag-drop uploader on the single product page.
   Components: drop zone, file table, progress bars, summary, cart list.
   Uses CSS custom properties that inherit from the theme when available,
   falling back to sensible defaults for standalone use.

/* ─── Design Tokens ───
   Inherit from the active theme's CSS variables when possible (Thread and Film
   defines --color-primary, --radius, etc. in base.css). Fallback values ensure
   the plugin still looks good on themes that don't define these properties. */
