made the long waited animation when add new truck or truck is completed. mouse over the list prevents the list from changing, only the animations work. moved top menu buttons to the right sidebar to free some vertical space. license text on button hover, not fixed above

+# CSS design tokens — typography, spacing, and full colour migration
+
+## Context
+`src/styles/tokens.css` already defines semantic colour/radius/shadow tokens for
+two themes (`classic`, `cockpit`). But:
+- there are no font or spacing tokens: ~25 distinct font-sizes (7px…40px, px and
+  rem mixed), 9 font-family declarations, ~25 distinct padding/margin/gap values;
+- about half the stylesheets still hardcode colours (`#667eea` ×88, `#333` ×42 …),
+  so those screens ignore the theme — they stay light under `cockpit`;
+- `UserManager.jsx` styles itself entirely with inline `style={{}}`.
+
+Goal: every UI value (colour, font, size, weight, spacing) comes from a token, so
+the look is changed in one file. Report *output* keeps fixed values.
+
+## What stays fixed (not tokenised)
+Printed/rendered report output must look identical regardless of screen theme:
+- `ReportEditor/a4/a4Elements.css`, `a4/print/print.css`, `ReportEditor/print/print.css`,
+  `ReportEditor/elements.css` (text-mode report elements on the page)
+- colours in A4 element JSX (`a4/elements/*`), `calibrationReport.js`, `sampleData.js`, tests
+- the "paper" surface itself (white page in `A4Canvas.css` / `EditorCanvas.css`)
+
+The report **editor chrome** around it (toolbar, inspectors, config panel, character
+palette, kind chooser, page setup, selection handles/guides) *does* get tokens.
+
+Also left alone: `components/concepts/ScalesAppCyberpunk.css` (standalone mockup
+with its own private vars). `DataDisplay.jsx/.css` is not imported anywhere — dead
+code, flagged, not touched.
+
+## New tokens (in `:root` only — theme-independent, both themes share them)
+```css
+/* Type */
+--font-sans: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif;
+--font-mono: 'Courier New', Consolas, monospace;
+
+--fs-xs: 11px;  --fs-sm: 12px;  --fs-base: 13px;  --fs-md: 14px;
+--fs-lg: 16px;  --fs-xl: 18px;  --fs-2xl: 22px;   --fs-3xl: 28px;
+--fs-display: 32px;             /* big figures: the weight reading etc. */
+
+--fw-regular: 400; --fw-medium: 500; --fw-semibold: 600; --fw-bold: 700;
+
+/* Spacing — 4px grid with the half-steps this UI actually uses a lot (6, 10) */
+--space-0-5: 2px;  --space-1: 4px;   --space-1-5: 6px;  --space-2: 8px;
+--space-2-5: 10px; --space-3: 12px;  --space-4: 16px;   --space-5: 20px;
+--space-6: 24px;   --space-8: 32px;  --space-10: 40px;
+```
+A theme may later override any of these (e.g. a larger `--fs-display` for cockpit).
+
+**Snapping rule:** off-scale values snap to the nearest step (5→4/6, 7→6/8,
+14→12/16, 15/17→16, 20→22 for font, rem values converted at 16px). Expect ≤2px
+drift in places — that's the consistency we're buying. Values that are
+geometry rather than rhythm (1px borders, icon/checkbox sizes, fixed widths,
+`letter-spacing`) stay literal.
+
+**Colour mapping** for stray literals (add a token only if nothing fits):
+`#667eea`→`--accent`, `#764ba2` gradients→`--accent-gradient`,
+`#333/#2c3e50`→`--text`, `#555/#666/#888/#999`→`--text-muted`,
+`#ddd/#e0e0e0/#dee2e6`→`--border`, `#f5f5f5/#fafafa/#f0f0f0`→`--surface-sunken`/`--surface-hover`,
+`white/#fff`→`--surface`, `#fee/#c33`→`--danger-soft`/`--danger`, greens/oranges→`--success*`/`--warning*`.
+Likely one new token: `--backdrop` (modal overlay dim).
+
+## Phases (one commit each; done via `/dispatch` → react-expert-dev)
+1. **Tokens** — add the block above to `tokens.css`; `index.css` body uses
+   `--font-sans`, `code` uses `--font-mono`.
+2. **Screens already on colour tokens** — swap font/spacing literals:
+   `Main.css`, `ScaleMonitor.css`, `Header.css`, `History.css`,
+   `ExtraCombinationsTable.css`, `App.css`, `ReportPreviewModal.css`.
+3. **Hardcoded screens** — colours + fonts + spacing:
+   `NomenclatureManager.css`, `NomenclatureUI/*.css` (ManagementOverlay, EntryForm,
+   Dropdown, FormOverlay), `LicenseManager.css`, `Login.css`, `ChangePasswordOverlay.css`.
+   `UserManager.jsx`: move inline styles into a new `UserManager.css` (reuse existing
+   Main.css classes like `.extra-field`, `.vehicle-form-actions` where they already fit).
+4. **Report editor chrome** — `ReportEditor.css`, `Toolbar.css`, `ObjectInspector.css`,
+   `ConfigPanel.css`, `CharacterPalette.css`, `EditorCanvas.css` (non-paper parts),
+   `a4/A4Canvas.css` (non-paper), `A4Inspector.css`, `A4PageSetup.css`,
+   `A4KindChooser.css`, `A4ReportEditor.css`; chrome colours in `A4Canvas.jsx` /
+   `A4Inspector.jsx` / `ObjectInspector.jsx` (guides, handles) → `var(--…)`.
+
+## Verification
+- After each phase: grep for `#[0-9a-f]{3,6}`, `font-size: *[0-9]`, px spacing in the
+  touched files → only allowed literals remain.
+- End state: hex colours exist only in `tokens.css`, the "fixed" report files, and the
+  concept page.
+- `npm run build` passes.
+- Visual: screenshots (Playwright, saved to `.claude/screenshots/`) of main screen,
+  nomenclature manager, login, licence, user manager, both report editors — in
+  `classic` and `cockpit`, before and after. Classic should look the same (±snapping);
+  cockpit should now be dark on the previously-light screens.
+- Test suite only when you say "ready for testing".

+ *                (or, with `distortMs` = 0, after `delay` -> entering).
+ *   distorting - the marker's last moment before the row opens. After
+ *                `distortMs` -> entering.
+ *   entering   - row is animating in. After `enterMs` -> stable.
+ *   stable     - normal row.
+ *   leaving    - row is gone from the live list but kept in place, marked.
+ *                After `delay` -> exiting.
+ *   exiting    - row is animating out. After `animationMs` it is dropped.
+ *
+ * `enterMs` defaults to `animationMs`; a value of 0 skips the entering phase
+ * (and `animationMs` = 0 skips exiting).
+ *
+ * `hold` (read live) parks the list while the user is pointing at it: a
+ * pending entry whose time is up stays pending (no distortion) and a leaving
+ * one stays leaving. Entries already distorting, entering or exiting finish.
+ * When `hold` turns false the overdue entries proceed in display order,
+ * `releaseStagger` ms apart.
+ *
+ * A row whose sort position changes becomes a `leaving` ghost at the old spot
+ * plus a `pending` entry at the new one. Each entry has its own timer.
+ * Content updates (same key, same position) apply immediately.
+ *
+ * Not staged: the first non-empty data (or any time nothing was shown), and
+ * bulk replacements touching more than `bulkThreshold` rows (a full reload).
+ * With prefers-reduced-motion the distorting/entering/exiting phases are
+ * skipped; the pending/leaving warning still lasts `delay`.
+ *
+ * `id` is unique per entry (a moved item briefly has two), use it as the
+ * React key. `getKey` may be an inline function.
