/* Bindingstone design system
 *
 * Software studio. Not editorial, not contractor-paper.
 * - Brand: rotated 4-square diamond, blue #0066FF, deep navy surface #0a1530.
 * - Type pair: Inter (brand font, present in all archived logo files)
 *   plus IBM Plex Mono for code-like accents.
 * - Hero polarity: dark by default. Sections alternate dark / light.
 * - Section openings use a small rotated blue square (mini-diamond),
 *   NOT the editorial hairline-bar + uppercase eyebrow used on the
 *   contractor client sites. Distinct visual signature.
