Statement
Dark mode and all mode differences shall be expressed through semantic token value swapping; component-level per-mode styling overrides shall be exceptional and explicitly documented.
Rationale
Keeps per-mode behavior auditable and intentional. Absorbs REQ-00041: centralizes both the token-swap mechanism and the exception policy in one requirement.
