specimen 01 — the shelf, two cover themes

Square, 1px border, no radius, no shadow. Hover and keyboard focus slide the preview panel up and draw a double-rule outline. Coarse pointers get the panel pinned open; prefers-reduced-motion drops the slide.

specimen 02 — the theme record

The renderer walks theme and calls setProperty on the tile — every key is optional and falls back to plain chrome. Adding post No. 004 with its own cover touches the data file only.
