/* ============================================================================
   IoTServa by VYROX - stylesheet

   Same family language as AiServa, with its own accent:
   - ONE theme: light. No section inverts.
   - ONE accent: signal teal. No second accent, no gradient text.
   - ONE radius scale: chip 12px, card/media 16px, panel 24px, pill for buttons.
   - Type: DM Sans display, Inter body, JetBrains Mono for addresses and numbers.
   - Motion: CSS transitions + IntersectionObserver only. No scroll listeners.
   - No sticky or fixed chrome: the header scrolls away with the page.
