/* Yuvera Solutions — parent-entity homepage.
   "Phygital Signal": a connected-products company built around the NFC tap-to-connect
   metaphor. An electric-lime signal cuts through a near-black (dark) or warm-bone
   (light) field. Syne (display) for architectural headlines, Hanken Grotesk (body),
   JetBrains Mono (technical labels). Concentric signal rings, a fine engineering grid,
   lime connective lines. Light + dark themes via [data-theme] with a header toggle.
   Fully crawlable, CSS-only — motion is progressive enhancement. */
