/* The door's look: the same stage the app's own welcome stands on.
   Asked for on 26 Sep 2026: the door redesigned and carrying the O.R.A
   logo. The page was a plain white card with the name in small grey
   capitals; the app it hands people to opens on a dark stage
   with the silver mark in a turning ring (src/components/ora-mark.css). So
   the door now looks like the thing it is the door to.

   Shared by / and /join. Dark only: the mark is silver and is drawn for a
   dark disc in every skin of the app, and on white it had nothing to stand
   on. No web fonts: a font fetched from anywhere else would tell a third
   party who opened an invitation, and the join page promises it reaches
   nothing but the update manifests.

   Every loop stops for reduced motion, at the end of this file. */
