fix(desktop): save the Print Layout composer in the project - #1994
Conversation
The Print Layout composer kept every setting in the dialog's own component state, and the dialog is mounted once for the life of the app. Nothing about the composed page was written to `.geolibre.json`, so reopening a project lost the title, page size, orientation and every other setting, while the composer went on showing whatever the previously open project had been composing. Add a `printLayout` section to the project format, backed by a `PrintLayoutConfig` in `@geolibre/core`: - The composer's controls seed from the open project's saved config, and the dialog is remounted on every project load, so an opened project's layout reaches the controls (and the previous project's does not). - Composer edits flow back into the store, so Save writes them. A write that changes nothing is ignored, so opening the composer does not mark the project dirty. - The section is written only once a setting differs from the defaults, so a project that never opened the composer serializes exactly as before. - A hand-edited or partial section is filled out from the defaults field by field, and a data or atlas block naming a layer the project no longer carries opens cleared rather than dangling. A blank title now follows the project name at draw time instead of being seeded into the field. Seeding it wrote to the layout (dirtying the project) just because the composer was opened, and a title seeded once went stale when the project was renamed. The Title field's placeholder shows the project name it falls back to. Per-session state stays out of the project: the captured map image, the current atlas page, export/clipboard notices and the dialog's panel widths. Refs #1992

- Keep a synthesized custom-legend id clear of every id the file claims, not just of the ones already accepted. An entry missing an id followed by one explicitly using the id that would be synthesized produced two entries sharing it, and the composer keys its swatch rows by id, so editing one row silently edited the other. - Drop an inverted or zero-area print extent. The draw tool orders its corners, so such a box only arrives from a hand-edited file, where capturing it would produce an empty image. Mirrors normalizeBounds in project.ts. - Floor the page border width at 1, the editor's own minimum: the border is drawn only when showPageBorder is on, so a stored 0 was an invisible "visible" border.

Overall the persistence design (normalize/scrub/equality-skip-dirty) is solid and well covered by |
Gate the atlas / data-table / chart "default the layer" effects on `open`, matching the auto-drive effect below them and their own stated intent. The dialog stays mounted while closed, so these ran in the background. That was inert when the composer's settings were component state, but now that they are project state, deleting a layer from the Layers panel would silently reassign the block's layer, push it into the store and mark the project dirty, with the composer never having been opened. Reopening it re-runs the defaulting, which is where the reassignment was always observable.

removeLayer (~line 1699) and deleteLayerGroup (~line 2047) already scrub storymap, widgets, comments, and legend for the layer id(s) being deleted, but neither calls the new scrubPrintLayoutForLayers (from print-layout-config.ts) on s.printLayout.
scrubPrintLayoutForLayers is currently only invoked in applyProjectToStore (project load). If a user deletes a layer that a Print Layout block references (tableLayerId/chartLayerId/atlasLayerId) while the composer is closed, and then hits Save without reopening it, setPrintLayout never runs (nothing changed the composer's own state), so the store's printLayout still carries the dangling layer id — and that dangling id gets written into the saved .geolibre.json. It only self-heals on the next project load or the next time the composer is opened (per the open-gated effects in PrintLayoutDialog.tsx), leaving a window where the saved file is inconsistent with its own layer set, unlike every sibling section.
Consider scrubbing printLayout alongside legend in both of these actions, e.g. printLayout: scrubPrintLayoutForLayers(s.printLayout, new Set(s.layers... )) (or a single-id variant mirroring scrubLegendForRemovedLayers's two call shapes).

This effect syncs layoutConfig into the store on every change, unconditionally (no open gate) — unlike the atlas/table/chart layer-defaulting effects below (lines ~1612-1641), which were deliberately gated on open specifically so that "an ungated reassignment would rewrite (and dirty) the saved layout in the background... with the composer never opened."
There's one pre-existing effect in this file that isn't covered by that gating and writes to a tracked config field regardless of open:
useEffect(() => {
if (!isMmPage && atlasExtentMode === "scale") setAtlasExtentMode("margin");
}, [isMmPage, atlasExtentMode]);(around line 1682). It runs on the dialog's initial mount too — including the mount that happens on every project load (via the key={projectGeneration} remount in TopToolbar), before the user has opened the composer.
Since the dialog is mounted unconditionally (open only controls the Dialog's own visibility, not whether PrintLayoutDialog itself is in the tree), a project file whose printLayout.atlasExtentMode is "scale" while paperSize/customUnit don't resolve to an mm page (only reachable via a hand-edited .geolibre.json today, since the live UI keeps these in sync) would: normalize fine on load → seed atlasExtentMode: "scale" into state → this un-gated effect immediately flips it back to "margin" on mount → layoutConfig changes → this setPrintLayout effect writes the corrected config back to the store → isDirty becomes true, purely from opening the project, with the composer never having been opened by the user. That contradicts the PR's stated goal ("opening the composer is not an edit") and the open gating pattern used elsewhere in this same file.

…1995) Follow-up to #1994, which landed before these two review findings could be folded into it. - Scrub the Print Layout data/atlas blocks in removeLayer and deleteLayerGroup, alongside the storymap/widget/comment/legend scrubbing already there. Deleting a layer a block referenced, then saving without reopening the composer, wrote a dangling layer id into the project file; it only self-healed on the next load. Adds scrubPrintLayoutForRemovedLayers, the delete-time counterpart of the load-time scrub, matching scrubLegendForRemovedLayers' shape. - Gate the "fixed scale needs a physical page" correction on `open`, the last effect still writing a persisted field ungated. It also runs on the mount that every project load triggers, so a hand-edited file pairing a pixel page with scale mode would be corrected, and the project marked dirty, before the composer had ever been opened. Refs #1992
Reported in discussion #1992: the print layout ("mise en page") is not saved with a project. Reopening a project loses the title, page format and orientation, and the composer instead keeps showing the layout of whichever project was open before.
Cause
PrintLayoutDialogkept all ~80 of its settings in component state, and the dialog is rendered unconditionally fromTopToolbar, so it is mounted once for the whole app session. Nothing about the composed page was ever written to.geolibre.json(only the composer's legend customizations were, via the separatelegendsection). Loading a project therefore neither restored a layout nor cleared the previous one.Change
A
printLayoutsection on the project, backed byPrintLayoutConfigin@geolibre/core:key={projectGeneration}), so an opened project's layout reaches the controls and the previous project's does not. The remount also drops the previous project's captured preview image.setPrintLayoutignores a config equal to the one already stored, so opening the composer does not mark the project dirty.One behavior change: a blank title now follows the project name when the page is drawn, instead of being seeded into the Title field on open. Seeding wrote to the layout (dirtying the project) just because the composer was opened, and a title seeded once went stale if the project was later renamed. The field's placeholder now shows the project name it falls back to.
Per-session state deliberately stays out of the project: the captured map image, the current atlas page, export/clipboard notices, and the dialog's panel widths.
Verification
Driven in a browser against the dev app, in both light and dark themes:
REPRO 1992/ a3 / portrait.printLayoutsection: title, subtitle, A3, portrait, narrow margin, page border on and north arrow off all came back, and the preview rendered them.npm run build,npm run test:frontend(6341 pass) andnpm run test:frontend:coverage(gate passes; the new module is at 100% lines / 100% functions) are green. New tests cover the normalizer, the default-omission rule, the layer scrub, and the project round trip including the "loading another project resets the composer" case.Refs #1992
