Theming

Three collections re-theme everything without touching components. Set the mode on the top frame (Figma) or an attribute on an element (code):

Collection	Modes	Code
Brand	Atomus · Example — Violet · (your brands)	data-brand="violet"
Color	Light · Dark	data-theme="dark"
Radius	Default · Sharp · Round	data-radius="sharp"
Spacing & Layout, Typography	Desktop · Tablet · Mobile	media queries (automatic)

Add a client brand: add a mode to Brand, point brand-25 … brand-950 at the client ramp (add the ramp to _Primitives first). In CSS, copy the [data-brand="violet"] block.
