- win95: a callback to Windows 95's grey-and-blue.

How the live preview works
Themes in GDLauncher are pure CSS custom properties (variables) applied at the document root. Hovering a card replaces the running values with the hovered theme's, so the change is instantaneous and reversible just by moving the cursor.
This is the fastest way to compare: walk through the cards with your mouse, see which one feels right, commit by clicking.
Themes are appearance-only
Switching themes doesn't change any setting or behavior, only colors. Instance settings, accounts, modpacks, all of it stays put. The theme is a stylistic choice, switch as often as you want.
What's coming
The Appearance page has a section labeled "Custom themes" marked as Coming soon. The intent is to let users import or build their own themes. For now you're limited to the six built-ins.
