/* About page. Loads after site.css, on /about only.
   Look: a soft canvas (near-black in dark, warm cream in light) with a glossy brand-teal object with white highlights drawn in
   WebGL as a fine halftone, fixed behind the page and turning as you scroll. Headlines are very large and set in two
   weights (light, then a bold line), with mono tags like "[ 002 / 004 ]", a running list, words that fly past, a frosted
   numbered card and the brand name in particles. Without JS everything is a plain, complete page; .fx (added by
   about.js when motion is allowed) turns on the sticky scroll scenes. Logical properties keep RTL correct. */
