/* ============================================================================
   case-personal.css — the two personalised blocks on a case study page
   ----------------------------------------------------------------------------
   Loaded by every page in src/projects/, next to whichever case-study
   stylesheet the page uses (the shared one or hotel-game's own). Rendered by
   src/js/case-page.js via src/js/personalize.js. Every --cs-* token has a
   fallback so the blocks look the same on a page that never defines them.

     1.  Personal comment banner   .cs-persona     (from an invite)
     2.  AI Summary                .jh-cs-summary  (from a typed goal)

/* ── 1. Personal comment banner ──────────────────────────────────────────── */
/* Jonas's note for this case, written per invite in the admin tool and filled
   in by renderPersonalComment(). The markup ships with the `hidden` attribute;
   JS removes it and adds .cs-persona--on when an invite has a comment for this
   page. Nothing else ever shows it. */
