/* The course catalog on the home page and the header of every course page.
 *
 * Handed off by Moe on 2026-09-02 (fellowship-redesign-handoff.zip). Two
 * things changed and nothing else: the home tiles became one bordered list,
 * two columns of rows with the instructor as the largest thing in each cell;
 * and the course page moved its instructor from a footnote under the syllabus
 * to a card at the top of the right column, above the pricing card.
 *
 * His stylesheet declared its own :root tokens (--bg, --gold, .pf-chip, .pfc-row…).
 * Those names collide with the rest of the site, so every rule here is scoped
 * under .pf-catalog (home) or .pf-pdp (course page) and reads the site's
 * --pf-* tokens from pf-theme.css. Icons are the site's masked SVG set
 * (.pf-i) rather than his inline <svg>s, per the icon rule.
