+## Presentation publishing
+
+Presentation PNG source (user instruction, 2026-09-23): all PNGs to import come from
+`/Users/mp/Desktop/ScreenshotPresentation/ThothIIScreens/`. This is the verified on-disk
+path the user refers to as `desktop/screenshot/presentation/thothIIscreens`.
+Copy supplied files unchanged into `presentation/deck/screenshots/thothii/`, preserving
+their embedded annotations. The 12 slide 11 PNGs are numbered `01` through `12` in
+popup order, in both the source folder and the deck. The first popup uses
+`01-StartingPoint.png`; popup 2 uses `02-Disambiguation01.png`. Refresh the image
+cache version when replacing a PNG. During the current editing session, refresh both
+operational browser windows after every modification, as explicitly requested.
+Popup 3 uses `03-DisambiguationFinal.png`, popup 4 uses `04-SchemaLinking01.png`,
+and popup 5 uses `05-CloseSchemaLinking.png`. Popups 6–12 are CTE planning, CTE 1,
+Final SQL, Datamart, Saving memory, Final step, and Back to start.
+The HTML references PNGs by relative URL: they are external static assets, not
+compiled or embedded. Keep `presentation/deck/screenshots/thothii/` with the deck;
+the Desktop source folder is not a runtime dependency.
+On 2026-09-23, the complete source folder was backed up to
+`/Users/mp/Desktop/ThothIIScreens-backup-20260923-FkCqV3/` and verified by SHA-256.
+The four unused PNGs (original prefixes 02, 05, 09, and 10) were removed from the
+source folder and, on 2026-09-24, from the deck after verifying backup equality.
+The backup retains all 16 original PNGs under their original names. Renumbering
+preserved each file's bytes; the existing Starting point images in the source and
+deck differ and were each retained unchanged.
+On 2026-09-24, annotated PNGs 08–12 were updated directly in the deck and verified
+visually; these deck copies are newer than the Desktop source copies. Preserve
+them when importing images. Their image cache version is `v=5`. Presenter notes
+for popups 09–12 are also updated in `presentation/deck/index.html`. The two Snagit
+comment boxes in PNG 12 share the same horizontal centre (1676.5 px in the
+3830 px source image); their text is centred within each box.
+
+The user confirmed the public AritmoLab presentation and presenter console working on
+2026-09-20. Updates use the `feat/ai-etl-presentation` branch on Gitea: commit and push
+locally, then the user runs `git pull --ff-only origin feat/ai-etl-presentation` in
+`/var/www/aritmolab/presentation` on the remote server. No SSH tunnel is available;
+the user can operate an authenticated remote terminal in VS Code. Nginx routes are
+already configured, so ordinary slide updates need no Nginx reload. Exact URLs,
+paths, checks and cache behavior: [Presentation publishing](docs/operations/presentation-publishing.md).
