Rendering moves into a module Web Worker behind a latest-wins RenderClient with a watchdog and a handshake-based main-thread fallback. The preview shows the real PDF through pdf.js at 2x with zoom, page indicator, audit issues popover and a focus modal. A4/Letter and margin controls are frozen into each invoice at issue and can be saved as the default (migration M3). react-pdf and pdf.js are lazy-loaded; the main chunk shrinks from 1.8 MB to 0.5 MB. The HTML twin and its styles are removed.
