Fork of RavenOfSeven/LifeSafer_LowHealthWarning for OctoWoW
Only change vs upstream: lowercase the toc Title color escapes (|C... / |R -> |c... / |r) so the OctoLauncher addon browser renders the gradient name instead of the raw escape codes. Addon code unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
