/* Biochar Field · single page stylesheet · 2026-10-16
   folded from: project-allocation-identity.css, project-responsive-safety.css,
   biochar-field.css, project-cd-dtp-convergence-20260825.css,
   project-donor-legibility.css, sitewide-correction-r20.css,
   evidence-type-authority-r36.css, project-system-r47.css,
   project-cinematic-r23.css, biochar.css (in that order).
   Only declarations that take effect in some reachable state are kept, in their original cascade
   order (qa/stylesheet-fold: every width band, mouse/touch, reduced motion, no-JS, forced colours,
   menus, rail panels and sheet, scroll spy, batch tabs and keyboard focus, hover/focus/active).
   Loads after shell.css and project-system.css, and before the page's inline <style>.
   The project rail (project-navigation-r48.css) and the Biochar identity and hero-instrument
   rules follow the page rules, in the order those sheets used to load. */
