/* ESLPod notes — one stylesheet. Layout is built for a library of thousands:
   fixed chrome (topbar + player bar) and a scrollable, incrementally rendered list.
   Colours come from a token palette injected above (light / dark / auto), so every rule below must
   reference tokens — never a literal colour — or one theme will silently drift out of contrast. */
