/* LEARNLIB_1109 · learn.css — the Learn library's own pieces inside nourva.ai's docs frame. It stands on the docs' sheet
   (its --docs-* colours, its shell, index, search and reading typography) and adds what a film library needs: the home's
   art and cards, the film page's player (chapters on its bar, subtitles in 20 languages drawn by the page, a corner
   player while reading), the chapters under the film, the transcript, the guides to read and the next film; and the two
   mockups of the docs with their films. Buttons follow the Capsule rules: pills, one ink primary per card (white on the
   dark appearance, ink on the light one), tint · ghost · text secondaries, heights 52/44/36, chips 30, tags 22; no green.
   The player keeps the film's own left-to-right time in every language; its words take the page's language. */
