/* The LBRCrawl page. Round 19 (lbr-systems #628, design/2026-09-23-round-19/handoff/LBRCrawl Page.html),
   made ready to serve: the review strip and its script are gone, Instrument Sans is self-hosted
   (the console's pinned @fontsource package, SIL Open Font License: /fonts/OFL.txt), the sample
   tags are gone, and every inline style moved here so the page's CSP can be 'self' only. */
