 * RST-Laserumbau (faserlaserumbau.de) — statische Ablösung des alten WordPress-Onepagers (21.10.2026).
 * Kein CMS, kein Framework: reines HTML/CSS + ein kleines Skript (assets/js/site.js).
 * Look wie das alte The7-Theme: Rot #e13d3a, dunkles Grau, Roboto für Überschriften/Menü,
 * Open Sans für Text, Oswald nur für „LASER-UMBAU“. Schriften lokal (variable woff2, latin), keine
 * externen Dienste, keine Cookies.
 * Schriftgrößen je Schrift höchstens 3: Roboto 34/20/15 (mobil 28/20/15), Open Sans 20/16/14,
 * Oswald nur die Hero-Zeile.
