/* progshow_v1.1 · Programming Lab student apps showcase (programming-lab.html only). LOCAL concept, 2026-11-03.
   Built only from the site's own tokens: --font/--font-d, --ink/--muted/--line/--blue, --r-card/--r-pill, glass v1.1 --gl-*,
   .band/.wrap/.sec-head/.btn/.btn-primary and the existing orange .pp-btn-o (--pp-o #BF5508 / --pp-oh #A64508).
   Scoped under .ps-*. v1.1 (18:05): static screenshots only; try-it dialog and expander rules removed. Header, menus, Ted, footer untouched. Rollback = remove the css line, the .ps-top-link line + the #student-apps section. */
