/*
 * Sage — the company page at sage.show.
 *
 * Direction: a colour-press card. The logo is loud — four serif letters in
 * red, violet, blue and gold over a hand-painted infinity — so the page around
 * it is quiet paper and ink, and borrows only those four inks as accents. Every
 * coloured thing on the page is one of the logo's letters; nothing is invented.
 *
 * Its own file rather than site.css: site.css is Show Browser's system (the
 * six swirl inks). Sage is the publisher, not the product,
 * and the two are not interchangeable.

/* Type: Archivo for Latin headlines, IBM Plex Sans Thai for Thai and for body
   in both scripts. The site used Bodoni Moda, a high-contrast display serif:
   its hairline strokes made English headlines hard to read on screen, and next
   to Thai — which has no such contrast — the two scripts looked like different
   weights. Archivo and IBM Plex Sans Thai share an even stroke, so a headline
   reads the same whichever script it is in. */
