/* Keepsake opening and the invitation-card handover.
   Carried over unchanged from the original build except for colour: olive is now sage.
   The card border, monogram position (32svh, 15svh wide) and copy offsets are tied to the
   final 3D camera projection in scene.js, so treat these numbers as fixed. */
