+# Dashboard tables CSS handoff
+
+## What changed
+
+- `src/web/tailwind.css`
+  - Disabled Tailwind v4 automatic repository scanning with
+    `@import "tailwindcss" source(none);`; retained the explicit template and
+    `app.js` sources.
+  - Replaced the padded/max-width dashboard container with the specified named
+    `content`/`wide` grid and 1rem/1.5rem gutter variable.
+  - Let direct-child `.scroll-x` wrappers occupy the wide track and made their
+    tables shrink-to-fit between the content-column floor and wrapper ceiling.
+  - Removed the global `.scroll-x > table { min-width:max-content; }` rule.
+  - Kept `.num` alignment/tabular figures on headers and cells, while limiting
+    nowrap to `td.num`.
+  - Raised `.cell-wrap`'s maximum width from 24rem to 32rem.
+  - Added a pointer from the table rules to `docs/dashboard-tables.md`.
+- `src/web/static/app.css`
+  - Rebuilt from the Tailwind source and checked for reproducibility.
+
+No templates, JavaScript, reader table rules, preview rules, or rating-cell
+rules changed.
+
+## Generated CSS diff audit
+
+Compared committed and rebuilt CSS one closing brace per line with:
+
+```sh
+diff -U0 \
+  <(git show HEAD:src/web/static/app.css | tr '}' '\n') \
+  <(tr '}' '\n' < src/web/static/app.css)
+```
+
+The 177-line diff contained 111 removed and 12 added content lines (excluding
+the two diff file headers). The component-rule changes were exactly the table
+framework changes above: remove `.scroll-x > table`, replace `.dashboard`, add
+the three direct-child dashboard selectors, split `td.num` nowrap from `.num`,
+and change `.cell-wrap` from 24rem to 32rem. The remainder was removal of
+utilities, unused theme symbols, and supporting custom properties that had
+previously been emitted by repository-wide automatic source discovery. There
+were no unrelated added selectors.
+
+The rebuilt file shrank from 77,721 to 70,697 bytes. The documentation-only
+utility selectors `.line-clamp-3`, `.max-w-[32rem]`, `.min-w-[10rem]`, and
+`.pb-6` are absent. The semantic `.cell-wrap` component still contains
+`min-width:10rem` and `max-width:32rem`, and `.dashboard` still contains its
+requested `padding-bottom` declaration.
+
+## Verification
+
+- `npm run css` — passed.
+- `npm run css:check` — passed with no diff.
+- `cargo build` — passed after the final CSS build.
+- `cargo test --lib web::` — 135 passed; the two failures were
+  `web::dashboard::feeds::tests::a_duplicate_subscription_still_decides_the_row`
+  and `web::dashboard::feeds::tests::add_subscribes_and_records_the_miniflux_feed_id`.
+  Both failed at the test bind setup with the documented
+  `PermissionDenied` / `Operation not permitted` sandbox error.
+- `cargo fmt` — passed without changes.
+- `cargo clippy --all-targets -- -D warnings` — passed.
+- `git diff --check` — passed.
+
+An extra full `cargo test` required by the shared brief was attempted, but the
+filesystem ran out of space while creating another test archive before tests
+started. I removed only this package's generated artifacts with
+`cargo clean -p daily-epub` (2.0 GiB), then reran the complete user-requested
+command sequence above successfully. The full suite remains unverified; the
+focused web suite is verified subject only to the two allowed bind failures.
+
+## Deviations and open items
+
+There are no implementation deviations. I did not run the browser measurement
+script because the sandbox cannot bind a preview server, as independently
+confirmed by the focused test failures. Visual viewport measurement remains for
+the post-merge environment described in the shared brief.
