 A snapshot of **where the project is and how it works** — the authoritative reference for current architecture, implemented systems, conventions, and known debt. It pairs with [`Project_Roadmap.md`](Project_Roadmap.md), which is the forward-looking plan. When the two disagree, this document describes *what exists today*; the roadmap describes *what's planned next*.

 ### Combat & towers
-- `TowerCombat` (server targeting loop; `OnTargetAcquired`/`OnTargetLost`/`OnFire` events for future animation), `Projectile`, hitscan + projectile paths, Single/Splash/Chain target types, damage types, range indicator. **Air-targeting** done: `GroundedOnly` towers skip flying enemies. Range checks are **3D**.
-- `TowerPlacementManager` (server-validated placement queue), `Builder` build queue with staged construction/pause/cancel/refund, `BuildSiteVisual` ghosts, owner tinting, RTS selection.
+- `TowerCombat` (server targeting loop; `OnTargetAcquired`/`OnTargetLost`/`OnFire`/`OnAreaFired` events), `Projectile`, hitscan + projectile paths, target types **Single/Splash/Chain/AllInRange**, damage types incl. **Electric**, range indicator. **Air-targeting** done (`GroundedOnly` skips flyers). Range checks are **3D**.
+- `TowerPlacementManager` (server-validated placement queue) — `SpawnTower` now **seats towers flush on the ground from their mesh bounds** (`SeatOnGround`), so any pivot works (replaced the old hard-coded y=0.5). `Builder` build queue with staged construction/pause/cancel/refund, RTS selection, owner tinting.
+- **Construction-phase build visuals:** `BuildSiteVisual` swaps between an ordered set of phase prefabs as a tower builds — `ConstructionPhaseSet` SO + optional per-tower `TowerDefinition.ConstructionPhases`, with a project-default set and a legacy cube Y-scale fallback. `BuildSiteVisual` resolves its def via `TowerTypeId` (catalog), like `TowerInstance`.
+- **Tesla Coil tower:** Electric, `AllInRange` (zaps every enemy in range each 0.5s tick). `TeslaArcVisual` draws arced, crackling, HDR `LineRenderer` bolts that flicker, plus **real point lights** (emitter flash + per-impact lights at struck enemies, capped) so the electricity actually illuminates the scene — emission/bloom alone don't cast light.
 
 ### Enemies & pathfinding
 - `EnemyHealth` (replicated HP, damage types, `IsFlying`, held state), `EnemyStatus` (lingering effects: slow/DoT), `EnemyMovement` (A* path following, zone-leak attribution, death/sink sequence).

 ### Roguelike — tower deck & draft (the current focus)
 - **`PlayerTowerDeck`** (per-player): the growable set of unlocked `TowerTypeId`s. Starts at the base set (seeded by `WaveManager` from `TowerPlacementManager.startingDeck`); placement is gated server-side (`TowerNotInDeck` rejection); the HUD build grid reads the local deck and rebuilds live on change. **Merged to `main`.**
 - **Draft system (Slice 1 — spine + "new tower"):** `DraftOption` (abstract SO) / `NewTowerDraftOption`, `DraftPool` (scene singleton catalog), `PlayerDraft` (per-player offered set + pick/buy-roll RPCs), `DraftService` (server weighted-random generation + offer/auto-resolve). The **prep phase is the draft window** (wave 1's prep = the match-start draft); unpicked drafts auto-resolve at prep end. Gold **"Buy Roll"** purchases an extra roll any time. Non-modal HUD overlay. **On branch `feature/draft-system`, verified working in-engine; pending commit/merge as of session end.**
-- Three base towers exist as data: **Basic Arrow** (ground+air single-target), **Siege Cannon** (ground-only splash), **Wall** (2×2, no damage, maze-shaping). *(Coworkers have begun replacing the placeholder cube visuals with cones.)*
+- **Draft Slice 1 is merged** (it's in `main`/the active branch line, not just `feature/draft-system`). Tower content available to draft: **Basic Arrow** (ground+air single), **Siege Cannon** (ground-only splash), **Wall** (2×2 maze-marker), **Tesla Coil** (Electric AllInRange). Arrow/Siege have cone meshes; Tesla is a ProBuilder mesh. So the "new tower" draft finally has real content — starting deck vs. draftable pool is a live tuning knob.
 
 ### Paint system (PAUSED)
 - In-match paint (R/G/B + Reset) recolors owned towers and drives effects (Red=Splash, Green=Poison, Blue=Cold), server-authoritative. **Frozen** pending the roguelike reconciliation decision (it overlaps with systemic damage-type upgrades).

 ### Level authoring
 - In-engine `TD.Levels` authoring volumes (player zones, spawners, leak exits, goals) + `LevelData` + a bake pipeline producing walkability/placement/owner grids.
 
+### Rendering & post-processing
+- URP with **6 quality-tier RP assets** in `Assets/_Project/Settings/Render Settings/` (Mobile, PC, URP-Low/Medium/High/Ultra). **HDR** must be on per-asset (Quality section) for bloom/glow.
+- **Project-wide post-processing** via the `DefaultVolumeProfile` (Edit→Project Settings→Graphics→Default Profile) — a **grimdark grade** (ACES tonemapping, desaturate/contrast, Split Toning, Bloom, Vignette, Film Grain). It has **no per-property checkboxes** (it's the always-on baseline). **Gotcha:** scene Volumes (e.g. the URP-template `SampleSceneProfile` in `9Player`) override the default — remove/redirect them so the default applies everywhere.

 ### HUD & dev tools
 - `HUDController` (UI Toolkit): gold/wave/lives/leaks, scoreboard, minimap, selection portrait + context panel, build/paint command grid, build progress, match-end overlay, chat, buff menu, and the new **draft overlay**.
 - `DevWaveControls`: **F9 / "Force Next Wave"**, **F8 / "Grant Next Tower"** (dev stand-in for deck growth).

 - **Visuals are placeholder** throughout (primitive/cone towers, sourced enemy models). See roadmap art TODOs.
 - **Enemies lack idle animation support** — needs adding across all enemy prefabs.

+- **Tower footprint visuals don't fill their 2×2 space** — meshes read smaller than the tile area they occupy; should visually reflect the full footprint.
+- **Grimdark grade is in, but the scene fights it** — the post-processing reads correctly, yet the bright/flat-lit ice map (`9Player`) undercuts the mood. Grimdark needs a **lighting pass** (low ambient, hard moody key) and ultimately darker level art; post alone can't carry it.
+- **URP additional-lights budget** now matters — Tesla flash + per-impact lights stack across towers; watch the URP asset's Additional Lights "Per Object Limit" / Per-Pixel setting.
 - **Tower catalog is now a single source of truth:** `TowerPlacementManager.towerDefinitions[]` (by-index, = `TowerTypeId`). `TowerInstance` replicates that index and resolves via `TowerPlacementManager.GetDefinition`. *(The old by-name `TowerRegistry` was removed 2026-06-24 — add new towers only to `towerDefinitions` + `DraftPool`.)*
 - **Catalog index 0 is a reserved sentinel** (valid `TowerTypeId`s start at 1) — easy to forget when wiring the catalog in the inspector.
 - **Catalog-index identifiers aren't session-stable** — blocks cross-match persistence until a stable ID is added.
