/* ============================================================================
   LAB WORK INDEX — /labwork/
   ----------------------------------------------------------------------------
   Loaded after /styles.css, which supplies the tokens, both font stacks,
   .container, .site-header, .site-footer, .callout-bubbles, .watermark and
   the stage meter. Nothing here redefines a site value.

   This is the index, not a notebook: a notebook page has its own
   notebook.css. The prioritization prototype and its stylesheet are in
   archive/labwork-prioritization-v5/, out of the build until a finished
   tool ships.

   Plex Mono appears only in this file, on the small labels the design sets
   in it — STAGE, SORT, the per-stage counts and UPDATED.
