/* ============================================================
   Topic entry hubs (remaining-168 T01, owner review 2026-09-15; LOCAL PILOT).
   Pilots: /dc/how-claims-work and /dc/pay. Loaded after guide-reading.css and
   condition-hubs.css on those pages only; every selector sits under
   body.th-hub, so no other page moves.

   - Compact opening: the reading-shell hero with a smaller illustration and
     the Share row and Guide Advisor stacked tightly.
   - Journey cards (.th-card): the primary choices, a square contained
     thumbnail beside the title, full description, gold card border.
   - Reference cards (.th-ref-card): supporting destinations inside a gold
     group boundary (a reading-shell disclosure on long hubs, a static panel
     on short ones). One quiet neutral outline per card; the gold stays on the
     group. PROPOSED page-scoped exception to THE BUTTON LAW, pending the
     owner's visual review; not a sitewide rule.
