EllesmereUI

**Cooldown Manager:**
- **NEW: Track Any Item by ID** - Cooldown Manager's add menu gains a Custom Item ID option so you can track any item by its item ID, with its own icon, cooldown swipe, and bag count. Works on cooldown, utility, and buff bars.
- Each assigned bar-button buff glow gains an "Only In Combat" toggle so the glow only lights up while you are in combat.
- The active-state overlay on tracked icons such as Ebon Might now keeps custom icon shapes, recolors the correct border, and matches your duration-text font instead of drawing a plain square. Glow and border edits also apply live while the buff is active.

**Unit Frames:**
- **NEW: Power-Colored Bar Background** - The power bar background can now follow your power type color (blue for mana, yellow for energy, and so on), matching the power-colored fill. Available on main frames and boss frames.
- Boss frame health and power bars now use the same separate Fill Color and Bar Background controls with inline class, custom, and power color swatches as the main frames.

**Quality of Life:**
- **NEW: Hide Error Messages** - A new toggle hides most red error spam such as "Not enough rage" or "Ability is not ready yet", while still showing important alerts like a full bag or full quest log.

**Auras, Buffs & Consumables:**
- Fixed the Hearty Flora Frenzy food reminder using the wrong item ID, so it now tracks correctly.
