/* Ora site — shared foundation ("Desk 1984").
   Layout concept: the page is a 1-bit desktop. Every section is a classic window sitting on a
   dithered desktop pattern, under a menu bar. Hard pixel edges, 2px rules, offset shadows.
   The one place colour appears is motion: the six-stripe rainbow that sweeps the screen in
   full-page transitions and fills progress bars. */
