Download AI Chat PDF v1.1.0

Added

• The floating button is a split pill: PDF exports, the ⚙ half opens a PDF
  options card (same style as the progress card) with colours, paper size (A4 / Letter
  / chosen in the dialog), orientation, margins (normal / narrow / none), text size,
  header on/off, images on/off, the ⌘P / Ctrl+P takeover, reset button position and a
  Save PDF button. Paper, orientation and margins are written as an @page rule only
  while a print is staged.
• Userscript-manager menu: PDF options… (the individual toggles moved into the card).

Changed

• ChatGPT printed a blank PDF: on beforeprint ChatGPT mounts its own print document,
  and its body:has(> .printDocument) > :not(.printDocument) { display: none !important }
  rule sits in a cascade layer, which outranks an unlayered !important. The script's
  beforeprint listener (registered at document-start) now stops the sites' print
  handlers while it prints, the page is hidden with inline !important styles, and
  anything mounted into <body> during the print is hidden as well.
• Gemini lines overlapped and the end of the chat was cut: Chrome split tall column
  flexboxes badly across pages. Each copied message is now rewritten from the live
  computed layout — tall column flex / stacked grid containers become blocks (child
  alignment, gaps and blockified display kept), inline wrappers around in-flow blocks
  become blocks, scroll boxes get overflow: visible, masks and sticky/fixed
  positioning are dropped. Gemini's fade mask on the chat scroller no longer reaches the
  PDF.
• Claude's chat sat in a narrow column on one side: the outer app wrappers carried the
  sidebar width as padding-left. Wrappers at or above the chat's scroll container now
  lose their side padding and margins in the copy.
• Claude's answer action bar (copy / read aloud / rating / retry) was printed: its icons
  are icon-font glyphs, so the buttons were not empty. Private-use and format characters
  no longer count as button text, and buttons whose aria-label is a known action are
  dropped too.
• Grok code blocks were light text on a light background after switching to the light
  theme (tokens coloured for dark only). Code blocks where both the text and the
  background are light get a dark background in the PDF.
• Colours are read through a 1×1 canvas, so oklch() / color() values are understood;
  plain rgb() parsing is the fallback when canvas reads are blocked.
• The fallback stylesheet (managers without GM_addStyle) waits for <html> to exist
  instead of throwing at document-start.
