Sharp 0.3.0

• YouTube: new section in the popup with an on/off switch for youtube.com.
  Hide Shorts (shelf, sidebar entry, and any Short in feeds, search or
  notifications), hide comments, and show, blur or hide thumbnails. Hidden
  thumbnails keep the duration badge, laid as a slim strip on the card
• Greyscale: wash the colour out of the chrome, the content, or both, on X
  and on YouTube, from a Misc group in each section
• X: backing out of a post no longer lands you somewhere else. A post whose
  verdict is already known is collapsed before X measures it, so X's own
  scroll restore is right; the post at the top of the viewport is nudged back
  once if X still misses
• X: after a rebuild, X's "Thanks" cards for reported posts are recognised by
  the wire's order of timeline entries and dressed with the usual banner
• Popup opens on the section for the site in the active tab; the live dot
  follows each site's switch; saving says "Saved."; a worker from an older
  build is reported instead of silently dropping fields
• Content scripts from youtube.com are trusted by the worker; wire claims no
  longer trigger the per-mutation sync

Firefox

Sharp now builds for Firefox from the same source. It is submitted to
addons.mozilla.org and awaiting review; until it is signed, install
sharp-0.3.0-firefox.zip below through about:debugging → This Firefox →
Load Temporary Add-on, picking manifest.json from the unzipped folder.
Firefox 140 or newer.

Firefox hands out site access one origin at a time, so open Sharp and use
Grant access if it says it has none for x.com, youtube.com or your
provider, then reload any tabs that were already open.

sharp-0.3.0.zip is the Chrome build, unchanged. From 0.3.1 the two are named
-chrome and -firefox.
