/* Metre2 Earthworks - the dense docked workspace from the signed-off boards (10 Nov 2026).
   Openspace look with survey marking pink (#ff4f9a) as the accent and a dark loam title bar; cut is burnt orange and
   fill is blue, as data only. Light by default, a dark "site at night" mode. Inter for the interface, JetBrains Mono for
   every measurement - both bundled (fonts/, SIL OFL). Component styles shared with Print Imposition and Programme Studio. */
