/* Keltic Geomatics site styles.
   Layout concept: a survey plan sheet. Paper ground on a strict 12-column grid, title-block headings
   and mono figures for anything measured; deep forest bands carry the 3D field work.
   Deliberately a single light theme with dark bands, like the printed plans it borrows from. */
