/* Yuvera Solutions — parent-entity homepage.
   Quiet, structural, credible. One strong sans (Hanken Grotesk), near-white +
   charcoal, ONE restrained ink-blue accent. The distinctiveness is structure:
   the ecosystem tree, the LINQS technology diagram, the 2014 timeline — clean
   CSS, fully crawlable, no decoration, no motion. CSP-safe (no JS). */
