{{-- Editable Table — faithful re-expression of src/html/tables/editable.html.
     Same DOM/classes/ARIA; Alpine x-data moved from <main> to a wrapper <div>.
     The page-local <style> + inline axEditable() component script are kept in
     place so the global fn is defined before the deferred Alpine boot. --}}
