+**JW Player Branding Migration**
+
+- Purpose: replace legacy ViewShark branding inside the JW Player serialized config stored in `db_fileplayers`.
+- What it changes:
+  - `jw_logo_file` → empty (no external logo by default)
+  - `jw_logo_link` → your `site_url` (if set), otherwise empty
+  - `jw_rc_text` → `Powered by EasyStream` (uses your `site_name` if present)
+  - `jw_rc_link` → your `site_url` (if set), otherwise empty
+
+Run after your database is initialized (docker-compose up created the schema):
+
+- `php f_scripts/migrations/update_jw_branding.php`
+
+Notes
+- The script safely unserializes the PHP array, updates keys, and reserializes.
+- It only touches `db_name` in (`jw_local`, `jw_embed`).
+- If no change is necessary, it leaves rows untouched.
