/* PolicyForge (bp-lgpd) — "Sereno" identity. Vanilla, no build.
   Standalone product — NOT the BPSO Lab 2026 system. Its own everything:
   · light-first (dark works, but light is the star — kills the "dev tool" read)
   · deep teal #0f766e on cool paper — calm/trust/compliance, not cyber-neon
   · Sora (headings) + Inter (body)
   · preview = a sheet of paper with a letterhead strip, NOT a macOS code window
   The only thread back to BPSO is the footer signature + the quality bar. */
