/* canonical.cc — Lab share widget styles
 *
 * Standalone stylesheet so any lab page can include just the share-widget
 * styles without pulling in the full site CSS. (Capital-call-planner is a
 * built Vite SPA with its own bundled CSS; loading the full style.css would
 * conflict with its layout. This file is scoped to .lab-share-* so it's
 * safe to add to any page.)
 *
 * Pairs with /js/lab-share.js and the Jekyll partial _includes/lab-share.html.
 *
 * Three pieces:
 *   1. .lab-share-strip — inline strip dropped into a lab's hero
 *   2. .lab-share-fab-* — floating bottom-right share button
 *   3. .lab-share-modal — the lookalike "share this" post-results modal */
