   ct-helpdesk.css — the helpdesk (2026-09-25 redesign; customer help 2026-09-26)
   ───────────────────────────────────────────────────────────────────────────
   .ct-hd-*   shared pieces — avatars, messages, attachments, the composer,
              detail cards (staff desk + customer Support page)
   .ct-hdx-*  the staff desk's three-pane layout (queue · conversation · details)
   .ct-hub-*  the customer help hub strip (Help Center · Tickets · New ticket)
   .ct-hds-*  the customer Support inbox (list pane · ticket / new ticket / welcome)
   .ct-kbx-*  the Help Center (search hero · topic cards · nav · article · TOC)
   Everything is built on the --ct-* tokens (so light / dark / auto just work)
   and reuses the house controls (.ct-tm-* selector, menus + chips, .ct-btn,
   .ct-pill). Loaded globally by Brand (HEAD_END), after cartuul-admin.css.
   ⚠️ Phone blocks live at the END of the file (source order must win).
