Experience Cloud CSS
OmniScript Static Resource CSS Use in Custom Lightning Stylesheet File Name
Theme tokens (CSS variables used by the generated CSS)
OmniScript Setup design tokens Paste into OmniScript Setup > Lightning Design System Design Tokens

These lines style the OmniScript without any CSS file. Paste them all: Aura sites and Lightning pages read the --lwc- lines, LWR sites read the --dxp-g- lines, and SLDS 2 themes read the --slds-g- styling hooks. Each runtime ignores the prefixes it does not use. Salesforce notes that design tokens are not supported in Safari, so keep the stylesheet as your fallback.
