@@ -745,3 +745,5 @@ Newest first: the date, what moved, and the new overall estimate.
 - **2026-10-18 (renderer, hayro patches 19/35):** A mesh shading (types 4–7) is sampled over its own triangles instead of the whole path: a BricsCAD plan with 310 one-triangle `sh` fills took 2 s per 1024 px tile at every zoom (and hit the 20 s watchdog on a busy machine); now about 70 ms, so zooming into dense topology drawings stays fluid. Estimates unchanged.
 
 - **2026-10-22 (PR #3227 integration):** M11: integrate upstream `80b7d215`; retain partial target-version compatibility and upstream content-boundary and image-size regression coverage. Scope and estimates unchanged.
+- **2026-10-26 (M7, #4864):** Add text remembers its Format panel (font, bold/italic, size, colour, alignment, character spacing) across restarts, saved as `text_style` with the other settings; each field is validated on its own, so a damaged value keeps the current one. Tested through `persist`/`restore`.
