/*
 * Threads panel theme — matched to adk's CopilotKit chat (CopilotSidebar /
 * CopilotChat v2). That chat renders in the framework's default LIGHT look:
 * white surfaces, soft gray-200 borders, gray-500/600 muted text, a system
 * sans typeface, and a ~1rem rounded panel with smaller radii on controls.
 *
 * The threads panel is FORCED LIGHT on this `.threads-theme` wrapper so it
 * reads as part of the same kit as the chat even when the OS is in dark mode
 * (adk's chat is always light). These tokens drive the themeable drawer base
 * + ui/card + ui/button (see threads-drawer/THEME.md) — never edit the drawer
 * files; theme them here.
