Dynamic import() of extension modules from a content script makes Chrome log
'Unsafe attempt to load URL chrome-extension://...' on YouTube pages, which fills
the extension's error list even though the modules load (HTTP 200). The content
script is now one classic file built by 'npm run build'; web_accessible_resources
is no longer needed and is removed.
