Party / Raid Interrupt Tracker (Lite)

Shows a row of icons for player + party1-4, colored border = their class

Watches UNIT_SPELLCAST_SUCCEEDED for just those 5 units (cheap, no combat-log parsing, no per-frame polling)

Cooldown swipe + countdown number is the native Blizzard Cooldown widget, so it costs basically nothing

Icon desaturates while on cooldown, resets via a single C_Timer.After callback (not a loop)

/pi unlock to drag it into position, /pi lock when you're happy — position is saved between sessions

Event tracking now covers all possible unit tokens (player, party1-4, raid1-40) registered once at load — since those are fixed slots regardless of who's in them, there's no need to re-register when people join/leave, so it stays just as cheap as the party-only version

Tracks one "primary" interrupt spell per class (Kick, Pummel, Counterspell, etc.) — a couple of classes are talent- or pet-dependent (Priest's Silence needs a talent, Warlock's Spell Lock comes from a Felhunter). If your group runs something different, the spell IDs are all in one table at the top of the .lua file, easy to tweak.

Auto-detects your group: solo → just you, party → single row (as before), raid → grid that wraps at 5 icons per row and grows to fit up to 40
