Color system

Nord, adopted whole. The brand and the app cite one palette — Snow Storm ground under Polar Night ink by day, the inverse by night, frost for links, aurora for accents — and no bespoke wheel gets reinvented.

The sun is not a text colour

The accent lives in small graphics — icons, focus rings, the sun’s glow on the social card. Canonical aurora yellow #ebcb8b is sized for dark grounds; by day it drops to ink weight for the 3:1 graphics bar, and words that need action always get frost. (The golds this section once described are retired to git history.)

The whole workshop is themed from these tokens (--paper, --ink, --link, --accent…), and follows your OS between light and dark. The mark’s tile is the polar night #2e3440 with snow ink — the one piece of the palette baked into artwork.
