       to sit behind it. On mobile that's not reliable (login.php's top

    /* Root cause of the "page slides left / white space on the right"
       bug: this was a vw-based width anchored with a negative right
       offset inside .chat-widget's small fixed-size box (see
       style.css .chat-widget). vw units on mobile Safari can measure
       against a layout width that's wider than what's actually visible,
       and a negative offset pushed it further still — together, wide
       enough on some phones/orientations to make the whole page
       horizontally scrollable. Anchoring directly to the viewport with
       left+right insets (not a width at all) makes that impossible:
       the panel is always exactly "screen width minus 16px each side,"
       full stop, regardless of any vw quirk. */
