/* The portal help: the opener pill, the "Ask about this" links and the
   slide-over panel. Everything is scoped under .ax-help (the panel root) or
   .ax-help-ask (the links the script adds beside data-help elements), and
   uses the portal's own tokens from admin.css, so the panel follows the
   light and dark themes without any colour of its own.

   Layout
     .ax-help-bar ........ the floating opener at the bottom of the page
     .ax-help-layer ...... the side pane, fixed to the right edge; not modal
     .ax-help-panel ...... head / thread / composer, as grid rows
     .ax-help-msg ........ one turn: .me (the admin), .bot (the help), .sys (a notice)
     .ax-help-meta ....... the quiet "Looked at · Sources" line under a reply
     .ax-help-acts ....... link buttons, quick replies, follow-up chips, thumbs */
