/* === JWST Daily Preview app — self-contained reel + detail =========== *
 *
 * Flat merge of what used to be two files in the prototype tree:
 *   1) the reel top-page styles (theme tokens, chrome, timeline roller,
 *      panels, scroll progress)
 *   2) the detail lightbox styles (.lx-* classes for the full-bleed
 *      lightbox and the briefing Q&A panel)
 *
 * Both have non-overlapping class namespaces (.reel-shell / .panel /
 * .roller / .chrome on one side, .lx-* / .briefing* on the other), so
 * merging is a straight concatenation.
