/* TOEFL 2026 materials pages: what only TOEFL uses.
 *
 * Loaded after assets/redesign/redesign.css (the shared design system) and
 * assets/toefl/toefl-tw.css (the utility classes the hand-written page content
 * still carries, compiled by scripts/toefl_redesign/build_css.py). Three parts:
 *
 * 1. The TOEFL chrome: a more compact hero, the course card in the sidebar,
 *    the author photo, the course popup, the lecture card.
 * 2. The content column (.tn-content): the design's adjustments to the
 *    content's own classes - text colour and sizes, rounder cards, grids that
 *    fit their columns, tables, code, and the speaking/writing sample widgets.
 *    Every rule here is scoped to .tn-content and targets the classes the
 *    pages use, so it outranks the utilities without touching anything else.
 * 3. The blocks other scripts generate: the overview extras
 *    (build_toefl_overview_extras.py) and the blog index (blog_index.py).
