   PDF Tool Workspace — shared full-screen RTL layout
   ───────────────────────────────────────────────────────
   Reusable layout shell for client-side PDF tools:
   full-viewport page, right options panel, left preview
   area, page thumbnails, hero/dropzone, panel controls,
   download list and SEO block.

   Tool-specific styling (e.g. Split ranges, JPG cards)
   lives in each tool's own stylesheet and layers on top
   of these generic `pdftool` classes.
