/* loom.luciaos.com — one stylesheet, no imports, no webfonts. * * The same dress luciaos.com and luce.luciaos.com wear, because they * are one house: warm cream paper, warm near-black ink, taupe for * tracked-out uppercase labels, one rust accent, a high-contrast * editorial serif on display text over a system sans for prose. The * custom properties below are the language site's, value for value, * so a colour fixed in one place can be fixed in the other by * copying. * * Two themes from one set of properties: the system preference * decides by default, and the toggle stamps data-theme on to * win in either direction. The dark theme is designed, not inverted. * * What is *not* here is what this site does not have yet: no left * section list, no on-this-page rail, no search. Six pages read * top to bottom in one column. When there are enough pages to need * a section list, the language site's stylesheet already has one. */ :root { color-scheme: light; --ink: #1e1b16; --ink-soft: #5b5547; --ink-faint: #8a8275; --paper: #faf8f4;
