The home header carried -webkit-app-region: drag after <main> in the tree, re-adding drag over the graph chrome row's no-drag carve-out — Electron's mask applies carve-outs only to regions added EARLIER in the DOM walk, so the gear/search/coverage/import buttons dragged the window. Fix: a dedicated 52px drag-mask div placed FIRST in the home page DOM; every carved control (chrome row, node detail card, toggle) comes later and subtracts correctly. The header loses its app-region entirely — the mask routes the pixels, the header stays a pure pointer-events container. Retires the .lh-float-drag CSS class. Verified live in the Electron dev shell by the owner: chrome row, sidebar close button, logo, and window drag all work.

|

* 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).
