/* blueHealthcare screenshot lightbox — NEW FILE (2026-09-12).
   Additive only: every selector here is scoped to .hc-shot / .hc-lightbox-*
   so this file can be included on any healthcare page without touching
   assets/healthcare-style.css or changing layout on pages that don't have
   screenshots. Vanilla CSS, no dependency, reuses the --hc-* tokens already
   defined in healthcare-style.css (loaded first on every page that needs
   this file).

   Thumbnail affordance: cursor:zoom-in already exists on .hc-shot img in
   healthcare-style.css. This file adds a small always-visible "Enlarge"
   chip (helps touch users, who never see a :hover state) and a visible
   focus ring for keyboard users, neither of which changes the card's
   box size -- both are absolutely positioned over the existing image. */
