Every row begins as a plain family-name input whose placeholder names
the font actually in use - no Default branding. Focusing the input is
the user gesture that runs Local Font Access discovery; when the engine
grants it, the control upgrades to the searchable picker, popped open
when the swap lands under focus. Blocked or unsupported engines simply
keep the input.
