/* VENDORED — do not edit here. Synced verbatim from CVERInc/demodeck @ fbe18a2. This demo dogfoods its own spinoff: the control panel is demodeck's contract (.dd-* layout + control kit, retheme via :root --dd-* overrides — accent glows auto-follow --dd-accent via color-mix). To update, re-copy demodeck.css from upstream and bump the SHA above. bleedblend's teal retheme + brand bits live in bleedblend-panel.css. */ /* =========================================================================== demodeck — a polished dark "control panel" template for open-source demos. A premium header, a two-column layout, and a kit of dark-themed controls: segmented buttons, sliders, color fields (picker + hex), toggles, styled selects, popovers, a live console terminal, and a copyable code box. Pure CSS. Pair with demodeck.js for the interactive behaviors (copy, popovers, color sync, console logging) — or wire your own. Retheme by overriding the variables in :root below.
