v4: a playlist's edit form is a .form like the dump's, and its dumps keep the header's edges — the editor laid the cover beside its fields with display: contents, which on a phone left them a squeezed column, and drew its own inputs: the title and the slug both in bold large type, the description in another size, only the slug labelled, and a segmented control styled apart. It now stacks the shared fields, each under its label (Cover, Title with its counter, Link, Description, the visibility toggle), over the action row, as DumpEdit does, and takes the header's whole card. The dumps' drag handle and remove button took width from the cards, which sat inset from the header on both sides; they now sit in the page's side padding (--page-gutter, which .page-content now names), so the cards line up with the header at any width. Undo shows as a small btn-primary over the card it would bring back, instead of a third control beside it. CountedInput, VisibilitySegmented and the .playlist-edit-* rules had no other users and are gone. 669 frontend tests pass, and tsc, eslint, deno fmt, doc:lint and i18n:compile --strict are clean; checked in screenshots in all six styles at 390px, Kanagawa and Smooth at desktop widths too, Undo in Smooth and GeoCities.
