namespace AKSRT\{Domain} under src/AKSRT/, wire composer.json psr-4,
and slim bootstrap to helpers/modules/hooks only. Split multi-class
widget/gateway files, update admin contract audit paths, and document
the layout in ADR/README.
Wire product cat/tag archives to settings-driven sort and AJAX paging,
seller product options/video/params editing, revenue withdraw form and
order review submit — finishing remaining shop frontend gaps after buy-path.
