/* MB Development Center — layout and density (spec §8, §9, §37)
 *
 * Colours, type and shape come from --mb-* custom properties, which
 * /static/branding.css defines from the imported MB Branding artefacts. Every
 * var() here has a fallback so an unstyled page is still legible, never so that
 * a missing token silently becomes an approximated MB colour: which palette is
 * in force is stated in the interface, not inferred from the stylesheet.
 *
 * Layout rules that make §37 true:
 *   - no element is given a rigid viewport height; the page scrolls vertically
 *   - every grid track is minmax(0, …) so long content shrinks instead of
 *     pushing the document sideways
 *   - wide content (tables, transcripts, logs) scrolls inside its own panel,
 *     so the page itself never overflows horizontally
 *   - panels are aligned to the start of their row, so a short panel next to a
 *     tall one is not stretched and a tall one is never cut
 */
