/* ===== Crop Improvement Lab — field & lesion palette ===== Colors are sampled from the actual subject matter, not a generic theme default: paddy is a real muted field green (not neon), straw is the tan of a dried bacterial-blight lesion, rust is the necrotic lesion border, sage is the grey-green halo of a sheath blight lesion. Light is the default theme, so it lives in :root and needs no attribute; dark is the opt-in, carried by data-theme="dark" on and set by the toggle in the header (see theme.js, and the inline script in each page's that applies it before first paint). The homepage hero (animated field + its overlay) is deliberately EXCLUDED from theme-switching: it carries its own fixed palette in both modes rather than taking the page's. Light mode is a clear blue day, dark mode a night sky, and the theme toggle crossfades between them — but neither is driven by the --bg/--text variables below. The FIELD stays dark in both, which is what keeps the hero's light ink legible: a dark field under a bright sky is backlighting, not a mistake. Its own --hero-green/--hero-gold accents stay constant for the same reason. */ :root{ /* Tells the browser which way to paint the things IT draws rather than we do:
