/* Light only, by choice. Colour: hanji cream with traditional Korean inks (indigo, rose-red, pine).
   Layout: risograph prints pinned to a paper wall. Text column beside a tilted print, alternating sides, broken up by two-up pairs.
   Type: Black Han Sans headings, IBM Plex Sans KR text, three sizes (--fs-s, --fs-m, --fs-l) and two weights (--fw-regular, --fw-bold).
   Long-form guides add one size, --fs-h2, so a page of section headings doesn't shout. Guides have no callout boxes:
   a tip is a plain sentence, a dated status line uses the homepage's .news strip, and pictures are taped prints.
   Black Han Sans ships one weight, so headings use --fw-regular.
   Shared by the Korean page at / and the English page at /en/. The .alt gloss is the other language's word beside a heading or tile. */
