matching CHANGELOG entry, and a regenerated graphify map (2,059 nodes /

+Follow-up (`2026-07-29`): tag details popup redesign, same slice. The popup was
+read-only with a single Dismiss button and rendered its metadata as inline
+`<b>…</b><br>` markup inside the generic `#dialog` (`width: max-content;
+max-width: min(440px, 90vw)`), which squeezed hashes and long messages into a
+narrow, uneven column. Redesigned it with a dedicated `#dialog.tagDetails`
+variant: a structured `dl.tagDetailsFields` two-column grid (`max-content 1fr`)
+for label/value rows, a full-width `white-space: pre-wrap` message row, and a
+predictable `width: min(460px, 90vw)` so the panel no longer shrink-to-fits.
+Added three copy actions in a wrapping flex row — **Copy Tag Name**, **Copy
+Object Hash** (`type: "Tag Hash"`), and **Copy Tag Message** (`type:
+"Tag Message"`) — each reusing the existing `copyToClipboard` path; the
+message copy sends the joined subject+body. New l10n keys
+`action.copyTagHash`, `action.copyTagMessage`, `type.tagHash`, `type.tagMessage`
+across `en`/`pl`/`zh-cn`/`zh-tw`, and the copy-error `typeLabel` map gained
+`Tag Hash`/`Tag Message` for friendly failure labels. Dismiss remains the single
+primary action; the copy buttons are bound after `showDialog` returns (same
+pattern as `#dialogAction`/`#dialogDismiss`), and `hideDialog()`'s
+`dialog.className = ""` already drops the `tagDetails` class. Added a webview
+rendering test for the copy actions and a `dialogStyles` CSS regression test
+for the grid layout.
