   iris blades pivot at a fixed point on the rim rather than scaling a shape
   in place, so the opening spirals through the same pinwheel silhouette a
   real aperture makes (see js/script.js for the choreography). No-op when
   JS is unavailable, and skipped entirely under reduced motion. */

   same angle about their own pivots swings the shared vertices away from
   center, opening a 9-pointed hole while the pivots stay put on the rim.
   The transition itself is driven from JS (script.js), which needs
   different timing for closing vs. opening, so no transition is baked in
   here beyond the resting transform. */
