-## L1 — shared LICE drawing kit (the foundation)
-**Goal:** One shared **LICE-based design kit** — a role-based palette + a type scale + a
-component-draw layer — that every surface (the bank panel now, the VST editor + embed
-strip later) draws through, replacing flat `LICE_FillRect` blocks and raw-GDI `DrawTextA`
-with a modern dark look: gradient surfaces (`LICE_GradRect`), anti-aliased rounded controls
-(`LICE_RoundRect`/`LICE_Line`), cached anti-aliased text (`LICE_CachedFont`), and a full
-interaction-state model (rest/hover/active/pressed/dragging/focus/disabled) the current
-drawing lacks entirely. The B+spectral palette constants (DS-2) live in one constants block.
-No new dependency — LICE is the toolkit; WDL/vwnd reuse is assessed at build time per DS-1
-("don't reinvent the wheel"). CONTEXT.md §Phase L (design-system spec). Product framing +
-palette + directions + forks: `docs/product/visual-design-language.md`. **Verify LICE
-gradient/AA/font surfaces and the `LICE_CachedFont`↔`HFONT` lifecycle against
-`vendor/WDL/WDL/lice/lice.h` + `lice_text.h` before use.**
-**Verify:** CTest green on the pure layer (the theme/palette contrast-floor tests + the
-component geometry/hit-test helpers); in-DAW, the kit renders a modern dark button/row/
-surface with AA cached-font text and working hover/pressed states, drawn double-buffered
-with no flicker.
-**Depends on:** the existing `bank_panel` LICE surface (the first consumer). Nothing in
-Phase S — L1 stands alone on the extension side.
-
-- [ ] Pure `theme`/palette layer: role→color mapping (`bg/base`, `bg/panel`, `bg/cell`,
-  `text/primary`, `text/dim`, `accent`, `accent/hot`, `warn`) selected via **one direction
-  constants block** carrying the settled **B (Neon Console) + C spectral** values (DS-2),
-  so the direction is a single-file change. Unit-test that each text-on-surface pair clears
-  its WCAG floor (AA 4.5:1 body / 3:1 large + state indicators) — the "punch to the floor,
-  not past it" rule made testable. No LICE/host types.
-- [ ] Pure component **geometry/hit-test** helpers where not already owned: button rect,
-  slider track/handle geometry, list-row rect + hover hit-test (mirror of
-  `mode_switch`/`bank_grid`/`editor_geometry` — no LICE, no host types, CTest-covered).
-- [ ] Shell **draw kit** (LICE): `fillSurface` (micro-gradient + 1px inner highlight/shadow
-  — the vwnd trick that kills the flat look), `drawButton`/`drawSlider`/`drawListRow`/
-  `drawWaveform`/segmented-switch/tab draw, and a shared `text()` over a cached
-  `LICE_CachedFont` set (title/label/value-mono/micro). Owns the cached-font lifecycle.
-  Honors the interaction state model (rest/hover/active/pressed/dragging/focus/disabled).
-  Double-buffered draw preserved (draw to `LICE_SysBitmap`, single `BitBlt`) — the
-  "zero-jank" half of "speed is the selling point." **DS-1: assess WDL/vwnd reuse here at
-  build time** — reuse a vwnd piece (e.g. its scroll listbox) where genuinely cheaper than
-  LICE, else draw on LICE; keep hit-test geometry in the pure layer either way.
-- [ ] Retire the raw GDI `DrawText` path in `bank_panel` in favor of the kit's cached-font
-  `text()` — the single biggest "temple os → modern" lever. (The VST-editor/embed-strip GDI
-  retirement is L3, gated on Phase S — see below.)

 ## L2 — dock-panel layout redesign (extension-side; DS-3: thorough, not a re-skin)
 **Goal:** Redesign the docked `bank_panel` **layout** to house the *full* button/affordance
 inventory — including the buttons **M11 adds** — intuitively, uncluttered, and useful, then
