/* W02: sign-in provider buttons (login page, signed-out account page) and linked-account rows
   (account page). Marks are local SVG files in assets/providers/. The Google button follows Google's
   sign-in branding: the standard four-colour G on a white (light) or #131314 (dark) surface with a neutral
   border. NextMoe, Bangumi, VNDB and QQ use neutral monogram tiles and OneDrive a generic cloud glyph,
   because no vetted logo asset is available for them; text labels always name the provider. */
