The workspace owns the viewport; the page itself never scrolls.
The page is black, so the "view above normal" read comes from the rounded
white content panel, not from a drop shadow (a black shadow on black is
invisible). `--inset` is the single knob between "fullscreen, corners
intact" (default 14px) and "edge to edge" (0px). Sidebar and main scroll
independently, which is the behaviour a production shell expects. */
