/* "Most likely, and the plan B we talked about" (plan-b v002), owner-approved and locked 2026-10-29 (Daniel: "approved- you can give this to lead
   for publishing and ask for next assignment"; Codex plan-b v002). Site placement of the locked style.css: every rule scoped to .dio-plan-b, values
   unchanged. Dropped: @font-face (site fonts.css supplies Nunito Sans), :root/body rules, the private page width/margin of .pb-demo and its page media
   rule. The h1/h2/h3 rules style the h3/h4/h5 the site uses. The arch band masks with the site's own assets/arch-tile.svg; one 4.4 s pass after .2 s
   inside the 4600 ms clock, ending 0 0. Keyframes renamed pbw- so no other page rule can collide. */
