 * ══════════════════════════════════════════════════════════════════
 *  BOVARD ÉLECTRICITÉ — Feuille de styles
 *  Site vitrine one-page — Abondance, Haut-Chablais
 * ══════════════════════════════════════════════════════════════════
 *
 *  Aucune référence design fournie dans le brief — design original.
 *
 *  DIRECTION ESTHÉTIQUE
 *  ─────────────────────
 *  Univers : technique, précis, alpin. L'électricité évoque la
 *  rigueur, la haute tension, la nuit éclairée. La montagne apporte
 *  la minéralité et la sobriété.
 *  Registre : sobre, professionnel, rassurant — jamais froid.
 *
 *  PALETTE
 *  ─────────────────────
 *  --color-primary   : #1B3A6B  → bleu marine profond (confiance)
 *  --color-accent    : #2F7FE8  → bleu électrique vif (énergie)
 *  --color-dark      : #1C2330  → anthracite quasi-noir
 *  --color-mid       : #374151  → gris anthracite (texte secondaire)
 *  --color-light     : #F4F6FA  → gris très clair (fonds alternés)
 *  --color-white     : #FFFFFF
 *  --color-accent-muted : rgba(47,127,232,.12) (fond icônes)
 *
 *  TYPOGRAPHIE
 *  ─────────────────────
 *  Titres   : Barlow Condensed 700/800 — géométrique, technique,
 *             condensé → évoque les repères de tableaux électriques
 *  Sous-titres / UI : Barlow 600/700
 *  Corps    : Source Sans 3 400/600 — lisibilité maximale
 *
 *  ÉLÉMENT NON-CONVENTIONNEL
 *  ─────────────────────
 *  Le bas du Hero et le haut de la section Services utilisent un
 *  découpage diagonal (clip-path polygon) créant une rupture
 *  dynamique entre les sections — signature visuelle du site.
