## Recent Reductions
- 2026-06-13: DEBT-0036 was narrowed again. `Canvas::draw_merge` checkerboard
background shader setup and final merged-texture redraw setup now route
through `legacy_canvas_draw_merge_services.h`. The retained Canvas path still
owns draw-merge layer iteration, blend-gate branching, framebuffer copies,
sampler/texture binding, and draw ordering.
- 2026-06-13: DEBT-0036 was narrowed again. `Canvas::layer_merge` now reuses
`legacy_canvas_stroke_composite_services.h` for retained layer-merge
`kShader::CompDraw` binding and source/destination blend uniform writes.
