v0.54.0

Changed

• The Classic layout on current Reddit now looks like old Reddit instead of a
  tidied-up new Reddit. Measured against a live public subreddit, the home feed
  and a live thread rather than the fixtures, which had drifted a long way from
  what Reddit ships. Listing rows read title (domain), then submitted 3 hr. ago by author (or to r/name on the home feed), then bold grey 131 comments share text links with the overflow menu at the end of that line. The vote
  column paints old Reddit's 15x14 arrow glyphs in #c6c6c6 with the orange and
  periwinkle voted states and a 13px grey score; Reddit's outline SVGs stay in
  the shadow root, hidden, so the buttons keep their listeners and labels. Link
  posts without a preview get the link placeholder and text posts the document
  icon. The header's account corner is the pale box old Reddit had, reading
  want to join? sign up or log in, and the search field is a plain bordered
  box instead of a 40px pill. The community strip continues the header's blue
  with the name at 13px and Create Post as a flat bordered button; the Join
  control is old Reddit's small blue subscribe pill, reached two shadow roots
  deep. Community highlights are one line of links. The right rail is flat 12px
  panels, and declutter hides its related-posts, promotion and legal blocks. The
  thread page is the same listing row with the media under it: the back button
  and avatars go, the tagline is one 10px line, the title is 16px, the vote
  rail sits top-left, and the share control is the word alone. A media expando
  button sits left of the tagline like old Reddit's, and an opened expando
  grows the row instead of being clipped inside its 72px.

Fixed

• Every "N more replies" fold on a live thread printed twice. Reddit keeps a
  hidden permalink copy of the control beside the live one, and the stylesheet
  forced it visible.
• The outbound URL of a link post painted as bold 16px text across the author
  line. It is now the (domain) after the title, from the post's own attribute.
• An empty 38px feed-status box painted above every listing. Live Reddit ships
  the banner holding one whitespace node, which :empty counts as content.
• The empty flair host on every post drew a bordered box at the right edge and
  reserved 172px of the title line.
• The hidden-promotion count rendered below the fixed header on top of the
  community strip. It sits beside the logo now.
• A community-status emoji button in the home feed's tagline was squashed into
  a 2px bar. Old Reddit's tagline has no such thing, so it is hidden.
• The home feed's tagline lost its community link: the post's invisible
  full-post link also starts with /r/ and took the class first.
• A shadow host nested inside another root could never receive a stylesheet or
  its parts: documentElement.contains stops at the boundary, so the host read
  as detached and was dropped on the first sweep. Prepared roots are now swept
  for nested hosts, and attachment is read through isConnected.
