 Conflicts should be confined to `src/App.jsx`, `index.html`, `vite.config.js` and
 `package.json`. `src/transforms/` is entirely new and will never conflict.
 
+The fork also hides three things upstream shows, because a generic datasheet has
+nothing to say with them: the roster overview card and its charts, the unit
+composition, and the per-unit points cost. Those decisions live in
+[`src/fork.js`](src/fork.js) - another file upstream does not have - and
+`src/10th/Roster.jsx` reaches for them on as few lines as possible:
+
+- it imports `ShortSummaryTable` from `../fork` instead of `./ShortSummaryTable`,
+  a one-line change that leaves the render site untouched. The upstream
+  component is still in the tree, unused, so its future diffs keep applying.
+- `hideModelCount` is pinned to `HIDE_UNIT_COMPOSITION` instead of being a piece
+  of checkbox state.
+
+Only the two checkboxes and the `pts` span are deleted outright, so a merge that
+touches them will say so rather than quietly bringing them back.
