- Default subreddit badge background from transparent to opaque fill
(light: #fde8e0, dark: #3d2518) so page highlights don't bleed through
- Remove lingering "to" text node from tagline when subreddit is hidden
- Hide the <li> wrapping the comments link (not just the <a>) to
eliminate leftover whitespace in the flat-list
- Simplify popup: subreddit bg fields are now color pickers (no longer
need transparent text-input workaround)
