+## L1 — shared LICE drawing kit (the foundation)
+**Goal:** Stand up the shared LICE-based drawing kit that every Phase L surface (L2 dock
+panel, L3 VST editor) consumes — palette/theme module, pure component geometry/hit-test
+helpers, LICE draw shell, and retirement of the GDI `DrawText` path in `bank_panel`.
+CONTEXT.md §Phase L (Kit architecture). DS-1 (LICE + WDL, no external frameworks) and
+DS-2 (Direction B Neon Console + Direction C spectral) are the governing settled decisions.
+**Verify:** CTest green (`theme_tests`, `component_geometry_tests`). Each text-on-surface
+pair in the palette clears its WCAG floor (tested). `bank_panel` text routes through
+cached-font `text()` — GDI `DrawText` path retired. Double-buffer discipline preserved.
+
+- [x] **`theme`/palette module** (`src/theme.{h,cpp}`): role→color mapping via one
+  constants block (Direction B Neon Console + Direction C spectral, DS-2); WCAG
+  contrast-floor helpers + tests; interaction-state color model; spectral ramp. Pure;
+  no LICE types. New CTest target `theme_tests`.
+- [x] **`component_geometry` module** (`src/component_geometry.{h,cpp}`): button/slider/
+  list-row geometry + hover hit-test. Pure; no LICE or REAPER types. New CTest target
+  `component_geometry_tests`.
+- [x] **`draw_kit` shell** (`src/draw_kit.{h,cpp}`): LICE draw layer — `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.
+- [x] **GDI `DrawText` retirement in `bank_panel`**: all panel text now routes through the
+  kit's cached-font `text()`; raw GDI `DrawText` path retired (the single biggest
+  "temple os → modern" lever).
