Owner ruling on the empty graph (honesty principle — dead controls are lies): the top-chrome actions row now gates per control. - Import Notes renders ALWAYS (graph enabled) — the one action that works on an empty graph, the entry point itself. It used to hide with everything else, leaving the empty state a dead end with no entry. - Search + settings render only when the snapshot has nodes, and their appear-once mount carries a deliberate 200ms fade (graph-chrome-fade-in, globals.css — the settings-pop register, reduced-motion appears instantly). Computed animationName verified live. - The row's body is now the exported pure GraphChromeRow (the DeleteNodeBody pattern) — the no-match note's truth (visibleIds + snapshot) stays upstream, computed by the wrapper. - The empty-state placeholder copy is LEFT AS-IS (SCOPE rule: it already has copy — icon, title, and the session-mapping paragraph). Pins (tests/render-graph-chrome.test.tsx): empty → Import Notes present, search/settings absent, no fade carriers; populated → all three, exactly two fade carriers; the no-match note follows its upstream truth. SSR of GraphChromeRow both ways. Live-verified on :3001 with scratch data: empty graph → Import Notes only + placeholder intact; a real import through the button (file input via DataTransfer) → nodes land, search + settings fade in (computed chrome-fade-in on both carriers); wipe → reload → back to Import Notes only (the reverse path). Scratch graph restored byte-identical. 932/932, tsc/lint/build green.

* THE SKIN — wave 5. Design tokens, the single place to restyle the app.

|

* Mathematical soundness, per the owner's brief:
|
||
* - Tailwind's built-in 0.25rem (4px) spacing scale IS the rhythm — every
|
||
* padding/margin/gap in the app uses whole units of a 4px base.
|
||
* - The type scale below is a declared modular ladder (each --text-* token
|
||
* carries its own line-height); components never invent pixel sizes.
|
||
* - Radii ladder is 4 / 8 / 12 / 16px multiples of the 4px base.
|
||
* - Emphasis colors live in tokens (--lh-ink-strong / --lh-ink-italic) so a
|
||
* future settings UI reassigns them (configurable per the owner).

Electron merged chrome (owner, 2026-09-17). The system title bar is
|
||
hidden (titleBarStyle: "hiddenInset" in electron/main.cjs); the app's
|
||
own 60px header bands are the drag surface. Everything here is inert
|
||
in the plain browser — it keys off <html class="lh-electron">, which
|
||
SidebarProvider sets after mount when it detects the Electron shell.

- .lh-drag window-drag region — on a dedicated mask div in
|
||
home.tsx placed FIRST in the page DOM (the mask
|
||
resolves by DOM order, not z-index: no-drag subtracts
|
||
only regions added earlier in the tree)
|
||
- .lh-no-drag carve-out for interactive elements inside a drag band
|
||
- .lh-lights-gutter the sidebar LH band's traffic-light gutter: lights
|
||
end at x≈68, the wordmark starts at 80px (5rem)
|
||
- .lh-closed-toggle same gutter for the sidebar toggle when the sidebar
|
||
is closed — the lights are static, the toggle moves
