/* ciserex.com — version 3
   ───────────────────────
   Two grounds and one thread.

   GROUND. Every page opens in obsidian and resolves into paper. The dark is where the system is
   stated — the hero, what it judges, what it proves, the close — and the paper is where it is
   explained. A reader who scrolls the home page passes through dark, light, dark: that arc is the
   page's structure, and it is why no two chapters look alike even though the page carries eight.

   THREAD. On a wide screen a hairline runs down the left margin of the whole page, ticked with the
   chapter number, and fills violet as the reader descends. It is the act log drawn as furniture: the
   record is the one idea the product rests on, so the page is built on it too. Below 1080px it is
   not drawn at all — a decoration that would cost a phone its margin is not worth its meaning.

   TYPE is the system stack, so the site loads no webfont: on the machines this is read on that is
   SF Pro, which is the reference the owner asked for. The scale is deliberately violent — 11px
   monospaced labels against a 104px display — because bold minimalism is contrast, not emptiness.
   Sentences do the work; there is almost no ornament to hide behind.

   COLOUR is ink, paper and one violet, #664099, from app/ciserex/brand. An application's own colour
   appears on its card, its icon and its page, and nowhere else: thirteen colours on one page is a
   toy, one colour per product is a catalogue.

   Radius is hierarchical: 20px on a picture, 18px on a card, 980px on a pill, 0 on a rule. */
