+## 2026-10-29: t89 custom game cursors (Codex)
+
+- Finished interrupted work: hollow build arrow at the exact mouse, open coloured crosses for
+  nozzle/igniter/copy/cut/paste, existing drill cross, and native pointer on paused canvas.
+- Files: src/ui/previews.js, src/styles/style.css, test/{t_cursors.py,run_all.py},
+  docs/{DESIGN,TESTING,PROJECT_MAP}.md, tasks/t89* and this log. Map regenerated.
+- All 41 headless suites, 29 focused t_cursors.py checks and pixel test/play.py pass;
+  no page/console errors. Isolated pre-change build fails the cursor check as expected.
+  Browser tests needed host GPU access after sandbox world startup timed out.
+- Inspected shots/t89-{pixel,smooth}-{drill,nozzle,build,igniter,copy,cut,paste}.png and
+  extra drag/blow/zoom/menu shots: open aim centres, clear arrow and retained previews.
+  No simulation/worldgen changes; full browser suite not run. Ready for owner review.
