/*
 * CyberForge one-page site
 *
 * Palette (see cp2077-style-research.md):
 *   --cf-yellow  #F3E600  — CDPR-confirmed Pantone 3945C, used sparingly ("punctuation, not pervasive")
 *   --cf-cyan    #03D8F3  — community-consensus accent
 *   --cf-black   #000000  — near-black background
 *   --cf-ink     #0D0D0D  — slightly lifted surface
 *
 * Typography: Rajdhani (SIL OFL 1.1) self-hosted, mirroring CP2077's
 * documented in-game UI typeface.
 *
 * NB: no glitch effects. Research recommends "one glitch per view, two and
 * you're a MySpace page." We opt for restraint — the HUD-bracket motif
 * and yellow-on-black palette carry the aesthetic.
