 * styles.css — "warm, wooden plank, construction" theme.
 * Palette: lumber browns, kraft/tan ground, blueprint-navy accents,
 * safety-yellow tape measure. All texture is CSS/inline-SVG — no image files,
 * no external fonts, no CDNs. One warm theme by design (this tool should feel
 * unmistakably its own, not like a dark dashboard).
