uniform setup remain local to the preview node. Next slice should target the
remaining mix-pass material/setup orchestration without reopening the landed
preview live-pass, binding, sample, or final composite helpers.
- 2026-06-13: `NodeStrokePreview::stroke_draw_mix()` now routes retained
mix-pass material planning plus composite/pattern/dual uniform payload
assembly through `plan_legacy_node_stroke_preview_mix_pass(...)`, with
compositor coverage locking the retained preview mix adapter semantics for
composite-pass patterning and dual state. Mixer framebuffer ownership,
retained shader execution, texture binding, and final draw/copy ordering
remain local to the preview node. Next slice should target the remaining
mix-pass execution ownership without reopening the landed preview live-pass,

- 2026-06-13: `pp_paint_renderer_stroke_execution_tests` now also covers
retained texture-dispatch activation order and sampler-dispatch routing
across brush tip, destination, pattern, and mixer helper inputs. Next test
