* Placeholder: bold, slightly larger initial letter on the topic word; make
health (teal) and environment (leaf green) clearly distinct and show more hue

tab so upbeatbytes.com stays put.
* Use the new SVG back arrow on the account and admin top bars (matching the
article page) instead of the old "←" glyph.
