/* ─── Loaders ────────────────────────────────────────────────
   Three reusable loaders. Picked from /loaders.html.
   - .ld-arc      → inline arc spinner (currentColor-aware)
   - .ld-orbit    → centerpiece orbit dots (3 concentric rings)
   - .ld-skel-*   → article-card skeleton grid

   .pill.is-busy now uses .ld-arc via ::after so every busy
   submit button gets the spinner with no JS markup work. The
   button's own text is blurred + transparent so the arc reads
   as the focal point.
