/* ── wpimage/compressor ───────────────────────────────────────────────────────
   Ported from the prototype's "upload tool" rules. Values are the original's.

   Everything is scoped under .wpi-compressor, which is what lets the inner class
   names stay as the prototype wrote them (.dropzone, .result, .layer, .tag …).
   Unscoped, names that generic would collide with the theme within a release or
   two. The design tokens are declared on the root here rather than :root for the
   same reason — Brandy owns some of these names globally.                      */
