First public release.

santi.tab replaces your new tab with a wallpaper from any subreddits you
choose, and lets you reshape almost everything around it:

• Multiple subreddits, with flair, search, size and orientation filters
• Your own image URLs, or a plain solid colour / gradient instead
• Accent colour, dim, vignette, blur, saturation, zoom and slow pan
• Five bundled fonts, UI scale, nine clock positions, custom CSS
• Optional search bar, shortcuts and time-of-day greeting
• Pin, favourite and browse wallpaper history
• Rebindable keyboard shortcuts, and JSON import/export of every setting

Wallpapers refresh every tab, hourly, daily, or only when you ask.
NSFW content is hidden unless you turn it on.

Nothing is collected — settings stay in local storage, and fonts are
bundled rather than fetched from Google.
