The main toolbar gear's Theme submenu and Settings › Appearance › Theme preview the theme under the pointer after the same delay as Quick Switch Scheme, and closing without a choice brings the selected theme back. Choosing a theme while it was previewed left the preview flag on, so the start-up theme cache kept the previous theme; `setTheme` now ends the preview.
Import Theme from JetBrains IDE… lists one row per theme plugin and installs it without switching the theme, like any theme plugin install. It reads only the newest settings folder of each product, so folders left behind by upgrades don't list their plugins again.

Adds Solarized Light, Solarized Dark, One Light and One Dark as built-in themes across the workbench, editor, terminal and Mermaid, keeping the original palettes (MIT notices in THIRD_PARTY_LICENSES.md, mapping in docs/themes.md).
- Native window colours are read from tokens.css at build time (`theme_frame.rs`) instead of a second colour table.
- Startup restores the built-in palette before first paint.
- Editor schemes, the terminal and Mermaid refresh on switches between themes of the same kind.
- The plugin packages of the same themes are removed.
- A test requires every built-in palette theme to define each token (only listed ones may inherit from the base theme), so new tokens can't silently miss them.
