/* XenusTrade — site v3, built from the banner ("Luminous Weave")
   - Hero = the banner, alive: generative light filaments crossing behind a two-tone Tektur wordmark.
   - Technical plate language from the banner: edge ticks, registration crosses, "FIG. / PL." labels in Geist Mono.
   - Tektur for headings and the wordmark, Geist Mono for labels and code, Instrument Sans for reading text.
   - Abyss blue-green ground, glacial ice, Elysium cyan. Green only for a confirmed buy. */
