/**
 * SAES TECH — corporate.css
 * Overlay stylesheet that retones the brutalist base toward a clean,
 * enterprise-consulting aesthetic. Loaded AFTER style.css.
 *
 * Reversible: remove the <link> tag in index.html (and playbook pages,
 * if extended later) to restore the brutalist look.
 *
 * Design direction:
 *   - White / off-white surfaces, slate ink
 *   - Single deep-blue accent (trust + restraint)
 *   - Sans-serif throughout (no mono headlines)
 *   - Soft radii, subtle shadows
 *   - Generous whitespace; no hairline section dividers
 *   - No ASCII chrome (no [ ], no ▸, no _ cursor, no [01])
