Identity
Three layers carry RC3 across any host: a signature colour, schematic iconography, and a thin identity rule.
Ember
Red-orange · hue 32
Used as a scalpel. Ember marks identity, selection, and primary action. The same hue threads through link colour, focus rings, status dots, and the identity rule. Backgrounds and panels stay neutral.
Schematic
RC3 inherits lucide-react at the PRIZM site-wide 1.5 stroke-width. Domain symbols that lucide does not cover ship as custom inline SVGs to the same convention — 24×24 viewBox, 1.5 stroke, schematic outlines, currentColor stroke.
One line at the top edge
A 1.5px top border in the signature colour runs across every RC3 surface, paired with the RC3 mark and the active module name. Always-on — the identity carrier travels with the module regardless of host.
