/*
 * The Lucid site. One page, no framework, no third-party requests: the typeface is served from here.
 *
 * Design rules (the same language as the app: black and white, hairlines, one filled button, iA Writer Mono):
 *  - Spacing is a 4 px scale (--s1 .. --s10), type is a ratio scale of about 1.25 (--t-1 .. --t6); nothing else is used.
 *  - Colours are tokens; text on every surface keeps at least 4.5:1 (body) and 3:1 (tertiary), in both themes.
 *  - Radii: 8 (controls), 12 (cards), 16 (the window picture). Borders are 1 px.
 *  - Motion is a short fade and rise when a block scrolls into view; it is off when the visitor asks for less motion.
