Checklist

• New settings default OFF (no behavior change without opt-in)
• Zero cost while disabled: no events registered, no polling, no hooks doing work, no frames built
• Cheap while enabled: event-driven (no polling, no timer-based logic, no per-frame allocations)
• No writes onto Blizzard-owned frames (weak-table pattern used); HookScript/hooksecurefunc only, never SetScript on Blizzard frames
• Tested in-game on live; no version gates or pre-Midnight APIs added

The EllesmereUIBlizzardSkin/EllesmereUIBlizzardSkin_WindowPacks.lua is close to the limit of 200 variables.

Do you want me to refactor it to put more variables into tables in order to relax this a little bit?

Yo these stylizations have been intentionally left to external addons which have access to the ellesmereUI skinning api if they wish to add an ellesmereUI look

As for the variable refactor id be happy with that but it would need to be submitted as a new PR. Thanks for the contributions as always red ❤️❤️
