+# PR_26179_CHARLIE_031-sprites-picker-zoom
+
+Team: CHARLIE
+
+Mode: Batch governance stacked feature workflow
+
+Base branch: PR_26179_CHARLIE_030-sprites-undo-redo
+
+Branch: PR_26179_CHARLIE_031-sprites-picker-zoom
+
+## Summary
+
+Implemented Sprite Creator picker and zoom display controls. Picker reads an existing unsaved draft pixel color and updates the active editor color. Zoom changes only the canvas display scale through Theme V2 CSS and page-session UI state. No persistence, database, API, schema, browser-owned authoritative product data, or start_of_day files were changed.
+
+## Branch Validation
+
+PASS
+
+- Built on the previous stacked Sprite branch.
+- Scope stayed limited to Picker and Zoom display controls.
+- Move remains disabled/deferred.
+- No DB/API/schema changes.
+- No product data persistence was added.
+- No stale PR #219-#228 code was copied.
+- ZIP package created at the user-requested batch path.
+
+## Requirement Checklist
+
+PASS - Picker implemented for existing painted pixels.
+
+PASS - Picker updates the active editor color without mutating the canvas.
+
+PASS - Zoom display controls added for 100%, 200%, and 400%.
+
+PASS - Zoom is display-only and does not persist data.
+
+PASS - Move remains disabled/deferred.
+
+PASS - Theme V2 CSS used for zoom sizing.
+
+PASS - No inline CSS, script blocks, style blocks, or inline event handlers added.
+
+PASS - Targeted Playwright coverage updated.
+
+## Validation Lane
+
+PASS - `node --check assets/toolbox/sprites/js/index.js`
+
+PASS - `node --check dev/tests/playwright/tools/SpritesToolShell.spec.mjs`
+
+PASS - `git diff --check -- toolbox/sprites/index.html assets/toolbox/sprites/js/index.js assets/theme-v2/css/gamefoundrystudio.css dev/tests/playwright/tools/SpritesToolShell.spec.mjs`
+
+PASS - Runtime guard scan found no prohibited inline style/script/event-handler or stale placeholder text in touched runtime files.
+
+PASS - `npx playwright test dev/tests/playwright/tools/SpritesToolShell.spec.mjs --workers=1 --reporter=list`
+
+## Manual Validation Notes
+
+1. Open `toolbox/sprites/index.html`.
+2. Paint a pixel with Gold.
+3. Change the active editor color to Blue.
+4. Select Picker and click the Gold pixel.
+5. Confirm the active editor color returns to Gold and the canvas does not change.
+6. Select Zoom and click 200%, 400%, and 100%.
+7. Confirm the canvas display scale updates and no sprite data is saved.
