 ## Repo identity and current state
 
-The CMake project and binary are now named `reaper_reasampler`. This is **ReaSampler** — a per-project audio sample-bank capture tool. The MPE modules (`mpe_model`, `mpe_view`) have been removed. M0–M8 are complete (bank_model, peaks, capture offline+realtime, persist, bank_panel, insert, capture action family, RealtimeRecordBackend, tail T1+T2+T1-followons). Phase B multi-bank (B1–B5, B-cap), Phase D1/D2 Design View (D1–D5, D2-W1–W3-B), Phase V versioning/beta-channel (V1/V3, V4), M10 provenance + re-capture from source, Phase R Reclaim (R1–R3: prune-reconcile core, dry-run shell, guarded deletion + action + panel button), and M11 in full (batch capture, action-button strip + keybinding labels, conform-on-insert verified-extant, native OS drag-out) have all landed. M9 slots deferred indefinitely. The *discipline* — pure REAPER-free testable core split from REAPER-facing shells — is **preserved** throughout.

 CONTEXT.md is the authoritative spec and build roadmap. Read it first for any non-trivial task. Every REAPER API name cited there is correct-by-intent; verify argument order, types, and flag values against `vendor/reaper-sdk/sdk/reaper_plugin_functions.h` before use.

 - `batch_capture` — M11 pure batch-capture planner: maps a list of source ranges to ordinal capture units, drives per-unit capture via a shared `captureAndIndexOne` helper, and aggregates mixed results. No REAPER types at the boundary.
 - `action_buttons` — M11 pure action-button strip layout/hit-test: divides a strip rect into N action buttons, min-width overflow-hiding, label formatting with "(unbound)" fallback, `ActionButtonRect` struct. Mirror of `mode_switch` / `bank_grid`.
 - `drag_out` — M11 pure OS drag-out module: gesture-boundary decision (internal drag becomes OS-bound when the pointer leaves the panel client rect), path-list assembly with dedupe and missing-file skip. No REAPER types at the boundary.
+- `theme` — Phase L pure palette module (L1): role→color mapping via one constants block (Direction B Neon Console + Direction C spectral, DS-2); WCAG contrast-floor helpers; interaction-state color model; spectral ramp. No LICE or REAPER types.
+- `component_geometry` — Phase L pure component geometry/hit-test helpers (L1): button/slider/list-row geometry + hover hit-test. No LICE or REAPER types. Mirror of `mode_switch`/`bank_grid`.
 
 **REAPER-facing shells:**
 - `capture` — `ICaptureBackend` interface; `OfflineRenderBackend` (deterministic default) and `RealtimeRecordBackend`. Input: `CaptureRequest`. Output: finished file + populated `Sample` handed to `bank_model`.

 - `track_guid` — shared `MediaTrack*` → canonical GUID-string formatter; single source of truth for membership keys used by both the view shell and the actions layer.
 - `provenance_shell` — FX-chain identity queries via `TrackFX_*` / `TakeFX_*` APIs; collects source-item paths and parent-detection inputs to feed the pure `provenance` fingerprint builder. Stamps `Sample.provenance` on capture when every resolving source item maps by exact normalized path (case-folded on Windows) to exactly one bank sample; ambiguous/mixed cases record nothing conservatively.
 - `drag_out_win` — M11 OS drag-out shell: Windows OLE `DoDragDrop` / `CF_HDROP`, copy-only structurally (`DROPEFFECT_MOVE` not offered, no source-deletion path); macOS/Linux via `SWELL_InitiateDragDropOfFileList` (copy-semantics caveat documented — SWELL does not expose a drop-effect query). Driven by the `drag_out` pure module.
+- `draw_kit` — Phase L shared LICE draw shell (L1): `fillSurface` (micro-gradient + inner highlight/shadow), `drawButton`/`drawSlider`/`drawListRow`/`drawWaveform`, cached-font `text()` over four `LICE_CachedFont`s (kit-owned lifecycle), full interaction-state model, double-buffer preserved. Consumes `theme` + `component_geometry`. First consumer: `bank_panel` (GDI `DrawText` path retired in L1).
 - `actions` — registers the capture/placement/slot action family, the Design View action family (toggle active mode, activate Arrange/Design, tag/untag selected tracks, show-both), the multi-bank action family (create/rename/reorder/delete bank, evacuate, activate, move/copy/remove selected samples), and the Phase R prune action (`BANK_PRUNE_FOLDER` — dry-run-first, confirm-with-manifest, then `pruneDeletePlan`-guarded deletion; **the ONLY file-deletion authority in the system**); routes each to the modules above via the `command_id`/`gaccel`/`hookcommand` contract. Every bank index verb wraps its mutation in a batched REAPER undo point (`Undo_BeginBlock2`/`EndBlock2`, `UNDO_STATE_MISCCFG`) so one bank operation is one Ctrl-Z. The prune action writes no ext state and opens no undo point (file deletion is not REAPER-undoable).
