What it does

• Reads combat events and cast signals to detect cooldown usage.
• Resolves caster identity (GUID/name) to visible nameplates.
• Stores cooldowns by GUID, with controlled name-based storage when GUID is not yet resolved.
• Uses a short reappear fallback so known cooldowns can return faster when nameplates come back into view.
• Applies cooldown rules (base cooldowns, shared links, reset effects, spec modifiers).
• Supports class/category filtering to prevent class-spell mismatches.
• Shows category border colors and interrupt pulse highlight behavior.
