/* ───── Per-kind palette ──────────────────────────────────────────────
   The component sets data-colour-kind on the wrapper to one of
   audio | video | image | model (av tools map to video). Colour-coding
   the drop zone by kind gives the site a consistent visual language:
   every video zone looks the same across tools, every audio zone looks
   the same, etc.

   Each kind defines an --tu-accent RGB triplet; the rules below consume
   it to tint border + fill + icon. Per-tool CSS can still override via
   higher specificity (e.g. `.vr-app .vr-upload`).

   Note: `data-kind` on the wrapper is the SIZE kind for the JS size-gate
   (models route through the image size budget). `data-colour-kind` is
   independent so the palette stays truthful even when size routes
   through another bucket.

   Specificity .tool-uploader[data-colour-kind=X] = (0,2,0) beats the
   typical per-tool `.xx-upload` (0,1,0), so these colours reliably win
   over the common `border: 2px dashed var(--border)` pattern every tool
   copies. */
