 * Figma : 10132:209 (01 LA TÊTE) / 10132:263 (02 LE CHEF D'ORCHESTRE) /
 * 10132:319 (03 LES BRAS). Structure 2 colonnes 720+720 :
 *   Gauche (.kp-expertise__projects) : eyebrow numéroté + H2 62px (2e mot
 *     en blanc 50%) + tagline italique + label "Roles" + mini-grid projets
 *     (2x2 cards + 1 grande). Fond sombre.
 *   Droite (.kp-expertise__coverage) : tagline + "Coverage" label orange +
 *     liste services avec lignes séparatrices (certains items avec sous-texte
 *     ou mini-photo 80x78) + tagline + bouton CTA. Fond sombre par défaut,
 *     crème pour expertise 2 via modifier --light.
 *
 * Alternance damier : 01 dark | 02 light (crème) | 03 dark. Le modifier
 * .kp-expertise--light bascule SEULEMENT la colonne droite en crème (fidèle
 * Figma — la gauche reste toujours sur fond sombre).
 *
 * Placeholder PROJET : les images projets (5 par expertise) n'étant pas
 * fournies par Yann à date, on rend un placeholder dark uniforme tagué
 * "PROJET CLIENT - À FOURNIR". À remplacer par <img src=...> quand les
 * vraies photos arrivent.
 *
 * Auto-enqueué (kp-pattern-expertise, dep kp-tokens).
