/**
 * @name Braid Layout
 * @description Vastly simplified two-edge layout: folds the server rail into the sidebar, docks the full voice controls bottom-left, tucks header extras into a kebab menu, merges message runs into cards, and calms the chrome. One-key toggle (Ctrl+Shift+B) between Braid and the classic layout. Suspends itself while Mod Mode edits the layout. Pairs with the Braid / Braid Light themes, and respects every other theme: cosmetic shape rules use :where() so any [data-theme] override wins.
