 * Mobsh web terminal chrome.
 *
 * The terminal owns the screen; everything else is a restrained full-width
 * band in the charcoal/paper palette from docs/design.md. One typeface — the
 * bundled Nerd Font — for cells, labels, and controls alike: this is an
 * instrument, not a site. Chrome follows the OS light/dark preference; the
 * cell grid keeps its own fixed terminal theme.
