   - Research: the copy gets the room (wider column, larger type); one real photo from my
     high-school research slides instead of a large three-photo collage.
   - Research wall: six real research photos (.rw-grid--n6) instead of ten look-alike images.
   - Tutoring: larger copy, the two YouTube appearances as a small list, and an early button
     to the tutoring page; the teaching record is shorter (small photos beside the heading,
     the lesson steps on one line) so the film button is reached sooner.
   Copy comes from window.SITE (content.js / content.en.js). */

/* ---------- YouTube (2026-10-31, second pass): no empty space under the player ----------
   The list of videos used to be four 300px-tall cards (the old horizontal shelf's flex-basis,
   applied down a column), so it ran twice as long as the player and left a blank area under the
   one-line caption. On wide screens the list now ends where the caption ends: the four rows share
   that height, each a 16:9 thumbnail with the title beside it. Phones keep the short horizontal
   shelf (titles only), so they carry less but are not denser than the desktop. */
