record page: the read-only field copy button is a Tab stop that stays invisible (hover-only reveal), like the inline-edit pencil before #25883

Filing class: ① a user-visible defect (class a, public door: any record page in desktop read mode). It was found by the #25883 item 1 developer (os-dev-report 6427401124 on #25883) and is outside that claim's file surface.

What

In ui/packages/plugin-detail/src/DetailSection.tsx, the copy-to-clipboard button on a read-only, copyable field (around :772 on main) has opacity-0 group-hover:opacity-100 and nothing else. It is a real, focusable button, so a keyboard user's Tab stop lands on a control they cannot see. The inline-edit pencil a few lines up had the same defect; PR #26325 (Part of #25883) fixes it by adding group-focus-within:opacity-100 focus-visible:opacity-100, the classes RowActionMenu and data-table already use.

Expected

The copy button is revealed on keyboard focus as well as on hover, in the same way. Pin it the way #26325 pins the pencil (focusable, carries the focus-reveal classes, its .group is its own field), since jsdom has no layout.

Sequencing

The same file as #26325, on the plugin-detail landing line (#26055 → #26277 → #26325). Claim it after #26325 merges.

Related, noted, not in this card

The pencil's aria-label and tooltip read "Double-click to edit", which does not match keyboard activation. Fixing that needs a new key in every locale pack.
On touch screens neither control is ever revealed (pointer-coarse:opacity-100). That belongs with the mobile read row's edit path.

⛔ Not a claim, ⛔ not a dispatch. This card was in pm:queue without its own triage line, which keeps execution seats from claiming it (#26387).

Triage: lands in ui/packages/plugin-detail/src/DetailSection.tsx + a pin; rationale: p3, the copy button's twin of fix(plugin-detail): reveal the inline-edit pencil on keyboard focus #26325's pencil fix: the same focus-reveal classes, pinned the same way. Same file as fix(plugin-detail): reveal the inline-edit pencil on keyboard focus #26325, so claim it after fix(plugin-detail): reveal the inline-edit pencil on keyboard focus #26325 lands (the landing line in the body).

Premise: holds 2026-10-27T04:19Z at origin/main 6746140361: the copy button in DetailSection.tsx carries opacity-0 group-hover:opacity-100 with no focus reveal, while the pencil beside it now has group-focus-within:opacity-100 focus-visible:opacity-100 (#26325).
Serial constraints cleared: #25883 item 1 (PR #26325, same file) MERGED 2026-10-27T03:41Z. No open PR touches DetailSection.tsx. #25883 item 2 is back in the queue and is held behind this card on the same file.
Writes: PR only via the relay op pr_create; comments only via the relay write tools; ⛔ no GitHub MCP writes.

Seat's route: add group-focus-within:opacity-100 focus-visible:opacity-100 to the copy button, exactly as fix(plugin-detail): reveal the inline-edit pencil on keyboard focus #26325 did for the pencil. Pin it the same way: it is focusable, it carries the focus-reveal classes beside the unchanged hover reveal, and its nearest .group is its own field. Red first. Fixes #26329.
