/* MiCyte — micyte.com
 *
 * Palette is taken from a spore print: the deposit a mushroom leaves on paper.
 * Warm brown-black substrate, spore-paper white, spore ochre, spore violet.
 * Deliberately not a neutral near-black with one bright accent — the accents
 * here are earth pigments, desaturated, and each has exactly one job:
 * ochre = place and structure, violet = the network.
 *
 * Monospace is the DISPLAY face, not a code affectation: this system's central
 * artifact is a dotted address, so the address is what gets set large. The
 * serif carries prose (a field notebook next to a machine address).
 *
 * No web fonts, no build step, no external requests — the page is self-contained.
