/* CONTEXA website. Hand-written; no framework, no build step, no web font, no
   script or image loaded from anywhere else. One stylesheet for four pages.

   The page is black-ish on white by choice: the system sans, one link colour
   (the mascot's ink, #0e6e63), rules between sections, tables for numbers,
   <pre> for anything the code names. Dark follows the visitor's system
   setting; there is no toggle. Nothing here has a gradient, a shadow, a glow
   or a transition, except inside the reproduced card, which is the product
   and keeps its own look (see the demo block at the end). */
