/* =========================================================================
   kit/peek.css — the panel that opens when a lab card is clicked.

   Its own file rather than a block in kit.css, and deliberately: kit.css is
   referenced by 250-odd pages and nginx serves it as immutable for a week,
   so touching it means bumping a cache-busting query on every one of them.
   Only two pages show cards, so only two pages load this.
