/* Demo feed: it must look like the social app people know, not like NTK, or it
   confuses. So this page has its own stylesheet and does not load
   /assets/ntk.css: a white page, near-black text, grey #536471 for secondary
   text, thin #EFF3F4 dividers, round avatars, the usual post and reply layout
   with an action row of thin icons (our own, lib/icons.js), blue #1D9BF0 for its
   buttons, and the system font. No other app's name, logo or assets. The one
   thing that stays NTK's is the stamp button the web embed puts on a tag
   (/embed/ntk-embed.css). Dark mode follows the system, as such apps do. */
