 ## Verification
 
-- Exported `index.png` has the same 1024x1315 dimensions as the master. It is
-  re-encoded by the exporter to 32-bit RGBA (about 528 KB), so the bytes are not
-  identical; composited on black the two images differ by at most 5.8/255 on
-  0.11% of pixels, all with alpha below 20, i.e. invisible. The release keeps the
-  171 KB master in the repository and ships a gzip sidecar.
+- Exported `index.png` has the same 1024×1315 dimensions as the master. Godot
+  re-encodes palette images to RGBA, so bytes need not match the source PNG.
+- Web preset `html/export_icon=true` uses the project icon through Godot's official
+  exporter. It creates `index.icon.png` (512×512) and `index.apple-touch-icon.png`
+  (180×180) with the corresponding HTML links. No generated HTML patch or default
+  Godot favicon remains; both files are included in the immutable release/hash check.
+  Firefox's runtime favicon is a generated blob URL; decoded pixels were compared
+  with the exported PNG and match exactly (zero mean/max difference).
 - The exported shell contains no "Game engine" text and the splash image has an
   empty `alt`.
-- `html/export_icon=false`, so no favicon is exported: the browser tab still shows
-  a default icon. Using the mascot as favicon is a possible follow-up.
+- The legacy URL `/pub/zombie-fps/`, score API and `zombie_fps_*` localStorage keys
+  intentionally remain unchanged to preserve bookmarks and browser identity.
+- Native `user://` moves with the project name. `player_profile.gd` imports the old
+  sibling `Zombie Room FPS/zombie_fps_profile.cfg` only when the new profile is
+  absent, never modifies the source and never replaces an existing new profile.
+  Name, ID, best score and name-lock flag are retained; migration has isolated tests.
+  The actual local migration was also verified byte-identical, old file unchanged.
 - On a phone in landscape the splash is scaled to fit the height, so the mascot
   appears fairly small; a landscape variant (mascot beside the title) would fill
   more of the screen if that is wanted.
-- All eleven test suites still pass; this change touches no gameplay code.
+- `test_rebalance_branding.gd` checks title, icon, export setting and exact damage
+  values; `test_player_profile.gd` includes five non-destructive migration checks.
+  Both suites also pass in the GDExtension-free staging project.
