/**
 * templates.css — per-template SEO landing pages (/templates/<slug>), plus
 * the .hub-* classes reused by the hand-written "Popular Templates" section
 * on landing.html (there is no standalone /templates hub page — browsing
 * lives at /app/templates, the in-app Library).
 *
 * Visually mirrors the in-app Template Library (css/template-library.css):
 * same card shape, premium badge, difficulty pills, and language flags, so a
 * visitor landing here from Google doesn't feel like a different product.
 *
 * Desktop-first: no @media queries here (see templates.responsive.css).
 * Colours come only from CSS variables in color-palette.css.
