and draw-merge paths consume that material plan for destination feedback,
each-sample pattern, dual-brush, and final composite decisions, and
`NodeStrokePreview` now consumes the same plan for preview material decisions.
Actual retained OpenGL draw execution and preview texture-binding details remain
under `DEBT-0036`.
Canvas and `NodeStrokePreview` stroke sample execution also delegate optional
destination copy, brush vertex upload, brush-shape draw, and destination unbind
through `execute_legacy_canvas_stroke_sample`, creating the first retained
OpenGL stroke execution service seam. Shader setup, uniforms, RTT/texture
ownership, dirty-box policy, and retained callback execution remain under
`DEBT-0036`.
It also owns renderer API texture-format to
OpenGL internal/pixel/component token mapping, including depth-stencil formats,
for future backend texture objects. `Texture2D` 2D texture binding, upload,
