/* =========================================================
   SmileAge — Lightbox (shared component)
   -----------------------------------------------------------
   Scope: a reusable image-lightbox used wherever an event
   gallery appears (events.html and the single-event detail
   pages). Every class is prefixed "sa-lb-" — distinct from
   every other namespace on the site — so this file can be
   linked on any page without touching that page's own styles.
   Usage: add data-lightbox="<group-name>" to any <img> you
   want included; images sharing the same group value become
   one navigable set. js/lightbox.js builds the overlay markup
   automatically — nothing else to add to the page.
