+# Dashboard tables
+
+How every data table on the dashboard is laid out, and the rules a new table
+must follow so it never grows a horizontal scrollbar on a desktop screen.
+Everything here is plain CSS in `src/web/tailwind.css` plus four cell classes;
+there is no table library and no JavaScript involved.
+
+## The problem this solves
+
+A table used to be `min-width: max-content` inside a `.scroll-x` wrapper, and
+most cells were `white-space: nowrap`. Any table whose natural width exceeded
+the page column (80rem, ~1355px at the site's 110% scale) became a horizontal
+scroller, even on a 2560px monitor, and the columns that mattered were hidden
+behind the scrollbar. Wrapping columns were squeezed to their minimum while the
+nowrap ones kept everything.
+
+## The three rules
+
+1. **Tables get the whole viewport, everything else keeps the page column.**
+ `.dashboard` is a CSS grid with two named column spans: `content` (at most
+ 80rem minus the page gutters, exactly what the header uses) and `wide` (the
+ viewport minus the same gutters). Every direct child sits in `content`; a
+ direct-child `.scroll-x` sits in `wide`. The table inside a wide wrapper is
+ `width: auto` (shrink-to-fit) with `min-width` equal to the content column
+ and `max-width: 100%`, centred. A table that fits the page column therefore
+ looks exactly as before; a table that needs more grows, centred, up to the
+ viewport edge; the page itself never scrolls sideways.
+
+2. **Columns wrap before the table scrolls.** The `min-width: max-content` rule
+ is gone. A table shrinks by wrapping its text columns down to their floors,
+ and only when the floors alone no longer fit (phones, mostly) does the
+ `.scroll-x` wrapper scroll. Headers always wrap.
+
+3. **A cell declares what it holds, and nothing else decides its width.**
+ There are exactly four cell classes:
+
+ | class | use it for | behaviour |
+ | ------------ | -------------------------------------------------------------- | ---------------------------------------------------------------------- |
+ | *(none)* | short prose, names, tokens, badges | wraps at spaces |
+ | `num` | numbers, money, counts | right-aligned tabular figures; `td.num` never wraps, `th.num` may |
+ | `cell-tight` | timestamps, dates, ids, a single short token that must not split | `white-space: nowrap`. Nothing longer than ~20 characters |
+ | `cell-wrap` | titles, URLs, notes, messages, badge lists, anything free-form | floor 10rem, ceiling 32rem, `overflow-wrap: anywhere` |
+
+ Anything long that must not wrap gets an inner block with a Tailwind clamp
+ (`
`) inside a `cell-wrap` cell; the cell
+ ceiling bounds the column, the clamp bounds the row height. Do not put
+ `truncate`/`line-clamp-*` on a `td` itself (a table cell cannot be a
+ `-webkit-box`), and do not use `table-fixed` on a page-level table (fixed
+ layout needs a definite width and is silently ignored with `width: auto`).
+
+## Checklist for a new table
+
+- Wrap it in `
` (add `tall` for a 70vh vertical cap) and
+ make that wrapper a **direct child** of `` if the
+ table has more than a handful of columns. Tables inside `.card`, `.cards` or
+ `details` stay inside their box and just wrap/scroll there.
+- Give every `td` one of the four classes above according to its content.
+ When in doubt, leave it unclassed: wrapping is the safe default.
+- Never `cell-tight` a name, a title, a reason sentence or a free-text field.
+- Check the page at 390, 1280 and 2560px. At 1280 and above the wrapper's
+ `scrollWidth` must equal its `clientWidth`; at 390 a wide table is allowed to
+ scroll.
+
+## Measuring
+
+`docs/plans/briefs/dashboard-tables/measure.mjs` logs in as the dev-seed admin,
+visits every dashboard page at several widths and prints, per page, whether the
+document overflows and which table wrappers scroll. Run it against a seeded
+dev server (`cargo run --example seed_dev_db -- ./dev`) before and after a CSS
+change; the "scrolling" count for widths ≥ 1280 should be zero.

+# Shared brief — dashboard tables (2026-09-20)
+
+The operator sees horizontal scrollbars on most dashboard tables, even on an
+ultrawide monitor, because every table is capped at the 80rem page column and
+`min-width: max-content` forbids wrapping. The fix is a small, reusable table
+framework described in **`docs/dashboard-tables.md` — read it first; it is the
+spec.** Two tasks run in parallel in separate git worktrees:
+
+- `01-css.md` — the CSS side (`src/web/tailwind.css`, rebuilt `app.css`).
+- `02-templates.md` — the template audit (every `td` gets the right cell class).
+
+## Ground rules
+
+- Work only in the worktree named in your brief. **Never touch the main checkout**
+ at `/home/thallada/workspace/the-daily-epub`. **Do not `git commit`** (the sandbox
+ cannot write `.git/worktrees`); leave the work in the tree, the orchestrator
+ commits.
+- Styling lives in **`src/web/tailwind.css`** (Tailwind v4, `@apply` inside
+ `@layer components`, semantic colour tokens). After every CSS change run
+ `npm run css` (writes `src/web/static/app.css`, which the binary embeds with
+ `include_str!`). `npm run css:check` must print no diff at the end.
+- CSP forbids inline `
