The chains-overlay TopBar had dead drag zones (counts, around search, close gap) — cause: app-region subtraction resolves by DOM ORDER, not z-index; the graph chrome's lh-no-drag column came later in the DOM and punched holes through the overlay's drag band despite sitting visually underneath (z-40 vs z-10). Two laws, per the owner's standardization ruling: - AUTO CARVE-OUT (globals.css): inside any .lh-drag band, every native interactive element (button/input/textarea/select/a/summary/ [contenteditable]) is automatically a no-drag island — draggable anywhere that is not a clickable element becomes structural. Manual lh-no-drag is only for clickable non-natives. - THE OVERLAY DOM LAW: a surface containing a TopBar that covers other content must be the LAST child of its container — ChainTableOverlay moved after the chrome column (verified live: last child, after the column; auto-carve rule compiled; search/close/sidebar-toggle all still click).

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
|
||
(native interactive elements carve out AUTOMATICALLY —
|
||
see the auto carve-out rule below; manual use is for
|
||
clickable non-natives only)
|
||
- .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
