Subject: [PATCH 1/2] fix(images): open Masonry by default, keep a saved
 Default layout, crop portraits from the top (#451) (#455)

- A Default layout or Thumbnail size saved in System now reaches the next Images
  visit in an open tab (this tab or another): the last visit records the
  defaults it started from, and a value its toolbar never changed follows newer
  defaults. A toolbar choice stays the current view's own.
- Images opens in Masonry when the browser has no stored Default layout
  (gallery-settings.js DEFAULT_SETTINGS.workspaceLayout); stored choices are kept.
- Grid/List card art, Library card art, the inspector cover and the Tag image
  preview crop with object-position 50% 20%, so portrait images keep their top.
- D157 in TESTING.md; concept comparisons start from the concept's stored Grid.

+  instead of the concept's centre: it acts only when the image is taller than its box
+  (portraits keep heads and faces), and a wider image stays centred. Masonry shows the
+  whole image and keeps the centre. The concept comparisons (`openProduction`) and the
+  specs of the Grid's own geometry start production from the concept's state, a stored
+  Default layout of Grid (`startInGrid`, concept-inventory.mjs, only while the browser
+  stored nothing); the comparisons do not measure `object-position`.

+  (workspace-system.spec.mjs) cover it. A browser whose legacy gallery wrote the old
+  default (`"grid"`) keeps Grid until Default layout is changed or "Reset display
+  defaults" is saved.

Subject: [PATCH 2/2] fix(workspace): remove the 1-5 prompt rating from the
 workspace (#447) (#461)

The star is only for favorites (maintainer ruling 2026-10-28). The workspace
no longer shows or edits a prompt rating: no Rating field in the Library
editor, no stars on Library cards, no "Highest rated" sort on Images or the
Library, and no rating column or rated-images total in System > Statistics.

The editor never sends `rating`, so a workspace save keeps a stored rating
as it is. A saved view or Library visit with the retired rating sort opens on
Recently added. Data and API are unchanged; legacy pages keep their ratings.

Recorded as deviation D153 (amends D14, D23, D96); concept comparisons map
the concept through it.

+
+**D153** (maintainer ruling 2026-10-28: the star is only for favorites; the concept keeps
+a 1–5 rating): the workspace shows and edits no prompt rating. The concept's rating
+appears in four places, and production draws none of them:
+
+- Library cards: the concept's footer reads "★★★★★ · Used today"; production reads only
+  the last use (amends D23). `library-concept.spec.mjs` takes the stars and their " · "
+  out of the concept page itself before measuring (`dropConceptRatings`), so the footer
+  facts are compared at production's width; it first checks that every concept card had
+  them.
+- Sort: the concept's "Highest rated" is not offered on Images or the Library (amends
+  D14); the comparisons drop it from the concept's options. A saved view or a Library
+  visit that still names `sort: "rating"` opens on Recently added; the server keeps such a
+  view as it was stored.
+- Editor (New prompt, Edit recipe metadata, Create text revision): no `#recipe-rating`
+  "Rating" select; `library-editor-canonical-comparison.mjs` `mapConcept` drops the
+  concept's Rating field. The editor never sends `rating`. An edit sends only changed
+  fields, so a stored rating stays as it is; a new prompt and a text revision create an
+  unrated positive (the revised prompt keeps its own rating; the legacy admin page shows
+  the revision as unrated). A reuse that leaves metadata unapplied compares title,
+  category, tags and notes only. The edit token still covers `rating`, so a rating
+  changed on a legacy page while the editor is open is an ordinary metadata conflict
+  whose review shows no visible difference.
+- System > Statistics: no "Avg. rating" column and no "Rated images" total (amends D96);
+  `system-concept.spec.mjs` maps the concept's table without that column.
+
+Data and API are unchanged: the `rating` column (`CHECK` 1–5), `PUT
+/prompt_manager/prompts/{id}/rating`, `rating` in Library, Images and statistics
+answers, and the server's `rating` sorts. The legacy pages keep their ratings until the
+cutover (#334). Favorites (the image star) are unchanged.
+
+Tests: units `tests/js/workspace-library-editor-state.test.js` (a prompt rated 4 edited
+and saved keeps 4, no `rating` in any body, no rating field),
+`workspace-library-state.test.js`, `workspace-images-state.test.js`,
+`workspace-saved-views.test.js`, `workspace-system-overview.test.js`,
