Party Portraits Unit Frame/Buff Reminder Bar

v4.2 (Phase 5.0 – Player Resting & Combat Icon Integration)
- Introduced dedicated player-only state icon system, mirroring Blizzard’s default behavior:
    • Displays Resting icon when in an inn/city (replaces level text and ring).
    • Displays Combat icon when in combat (replaces level text and ring).
    • Automatically restores level indicator when neither state is active.
- Added independent topmost overlay frame to render icons above all UI layers:
    • FrameStrata set to DIALOG to ensure visibility over health bars and portrait rings.
    • Overlay dynamically follows the player’s level ring position each frame.
- Implemented secure, event-driven listener for:
    • PLAYER_UPDATE_RESTING
    • PLAYER_REGEN_DISABLED
    • PLAYER_REGEN_ENABLED
    • PLAYER_ENTERING_WORLD
- Optimized performance:
    • Listener permanently attached to player frame to prevent garbage collection.
    • Event-based updates only; no polling or excessive OnUpdate work.
- Added debug output for event tracing (optional; commented by default).
- Fully compatible with Overlay, Beneath, and Above modules.
- Verified complete combat safety (no protected function taint).
- Visual polish:
    • Icon size scaled to 30×30.
    • Precise offset tuning for alignment above health bar borders.
- Marks the beginning of Phase 5 foundation updates (v5.0).

v4.1b (Phase 4.1b – Overlay Target Restore Hotfix)
- Fixed issue where left-click targeting stopped working after toggling Overlay Off (Portrait Mode) until reload:
    • Corrected attribute assignment to `frame.__pp_button` (secure click layer) instead of parent frame.
    • Targeting is now immediately restored after `/pp over off` toggle.
    • Deferred rebinding logic added for safe restoration after combat (`PLAYER_REGEN_ENABLED`).
- Maintains full combat-safety compliance with secure templates.
- Verified no interaction issues between Portrait Mode and Overlay Mode toggles.
- Included required media folder in upload(oops)

v4.1 (Phase 4.1 – Final Pre-Config Polish)
- Added combat-safe guard for `EnableMouse()` calls to prevent rare `[ADDON_ACTION_BLOCKED]` taint:
    • Patched gear button mouse-enable logic with `InCombatLockdown()` check (line ~223, PartyPortraits.lua).
    • Prevents protected function errors when party members die or disconnect during combat.
- Added Phase 5 placeholder comment block for future buff-equivalence groups:
    • Example pair: Mark of the Wild (1126) ↔ Legacy of the Emperor (115921).
    • No behavioral change yet—serves as documentation for next-phase user-configurable system.
- Verified overlay stability, click-casting responsiveness, and hover logic unchanged from 4.0.
- Minor documentation and internal comment cleanup.

v4.0 (Phase 4.0 – Core Rebuild + Expanded Systems)
- Complete internal rewrite of PartyPortraits architecture for modularity, maintainability, and security.
- Introduced four logical layers:
    • **PartyPortraits.lua** – Core foundation (anchor frames, saved variables, slash commands).
    • **PartyPortraits_Overlay.lua** – Buff reminder overlay and click-casting layer.
    • **PartyPortraits_Beneath.lua** – Health & resource bar module (under-portrait bars).
    • **PartyPortraits_Above.lua** – Debuff indicator and role icon overlay system.
- Restored and stabilized **left-click casting** behavior:
    • Now functions in both Portrait Mode and Overlay Mode.
    • Secure click attributes set dynamically; re-applied safely after combat lockdown.
- Added **health and mana/resource bars** beneath each portrait:
    • Displays accurate current HP/resource for all visible party members.
    • Bars update smoothly via OnUpdate interval loop (default 0.5s).
    • Fully compatible with locked/unlocked state, solo mode, and overlay toggle.
- Added **new visual layer above portraits** for debuffs, role icons, and custom indicators:
    • Compact 13px grid (3 columns × 5 rows) with Y-offset lift above ring.
    • Tooltip hover support and debug overlays for development.
    • Planned future use for crowd control and role display.
- Added **Slash Command Expansion**:
    • `/pp overlay on/off` – Toggle buff reminder overlays.
    • `/pp beneath on/off` – Toggle health/resource bar module.
    • `/pp roles on/off/debug` – Toggle and debug role icon overlays.
    • `/pp reset`, `/pp lock`, `/pp unlock`, `/pp hide`, `/pp show` retained.
- Implemented **robust SavedVariable defaults** and persistence for all module states:
    • OverlayEnabled, BeneathEnabled, ShowWhenSolo, Locked, AnchorPoint, and coordinates.
    • Automatic seeding of missing keys to prevent nil errors after patch updates.
- Introduced **secure toggle management**:
    • All protected calls (`EnableMouse`, `SetAttribute`, `Show`, `Hide`) now wrapped or deferred during combat.
    • Deferred queue automatically executes on `PLAYER_REGEN_ENABLED`.
- Added **debug utilities**:
    • `/pp roles debug` cycles through role icon display (HEALER, TANK, DAMAGER, NONE) even without party.
    • Tooltip overlay for above-layer icons aids in layout verification.
- Improved **visual and performance polish**:
    • Class-colored rings preserved with additive blending.
    • Smooth alpha fade and glow overlay updates.
    • Y-offset adjustments for better readability of icons above and beneath portraits.
    • Reduced redundant OnUpdate calls; single timer drives all visual updates.
- Introduced **internal debug mode** (`debugMode = false` toggle) for advanced testing.
- Established **modular namespace** structure:
    • `ns.Above`, `ns.Beneath`, `ns.Overlay`, and `ns.DB` tables safely separated.
    • Prevents cross-file pollution and allows optional file loading.
- Prepared groundwork for **Phase 5 – Config System Overhaul**:
    • Placeholder comments in Overlay for user-selectable spells.
    • Planned equivalence group support and in-game configuration UI (PartyPortraits_Config.lua).
