     applied automatically, but our own `position` override further down
     replaces it, so it has to be spelled out in full here). Previously this
     was `position: relative`, which put the dialog back in the document's
     flow and made the browser scroll the whole page to bring it into view
     every time it opened. A later fix tried `top/left/transform`, but with
     `inset`/`margin` left unset the browser's default `inset: 0` (which sets
     right/bottom too, not just top/left) and `margin: auto` stayed active
     alongside it — the two centering methods fought each other and only
     visibly broke once a dialog's content got tall enough. Setting `inset`
     and `margin` explicitly here removes that conflict for good. */
