/* lab.portolan.be — shared stylesheet
   Layout: a dark top band like portolan.be, then a single 720px reading column for text and a 960px stage for interactive pieces.
   Type: Libre Baskerville (as on the main site) for display and prose; a light sans for controls and labels.
   Colour: white page, near-black band, the sail mark's blues as the only accent. */
