   code-share-view.css — the Delphos Code share-link viewer.

   ── Why it is separate from delphos-code.css ──
   The recipient is not a Delphos user. They have no theme preference stored, no
   accent choice, and no signed-in session, so this view cannot depend on the
   runtime tokens ui-polish.js writes for a logged-in user. Every value here is a
   literal in the app's warm-graphite family, with the app's tokens used only as
   an OPTIONAL override — so it looks right for a stranger on a cold load and
   still tracks the theme when an owner opens their own link.
