From 64ccd1f829e1982e30f77e339c6bccfec6aeb62f Mon Sep 17 00:00:00 2001 From: Julian Appel Date: Thu, 6 Aug 2026 21:56:21 +0200 Subject: [PATCH] Add dark mode toggle in the sidebar Adds a persistent dark/light theme toggle (localStorage + data-bs-theme on ) so it applies globally, including the circuit editor route which has no visible sidebar. An inline beforeInteractive script sets the theme before hydration to avoid a flash of the wrong theme. Bootstrap components pick up data-bs-theme automatically; the custom circuit-grid CSS previously used ~150 hardcoded hex colors, all converted to semantic tokens in globals.css with light/dark values. Verified with a headless-browser pass across the project list, project detail page, circuit editor, project-device drawer and a settings modal in both themes; no console errors.
