Description: Independent US guides and cost calculators for ISO certification. Every price is shown as a plain-English USD range. A self-contained theme that auto-builds a guide page and a range-based cost calculator for every ISO standard from a single data file. Identity: measured — cool white, cobalt, and a green-to-amber range bar.

/* ============================================================
   DESIGN TOKENS
   Identity: "measured". The site's whole job is cost RANGES,
   so the range bar (green low -> amber high, ruler ticks) is
   the signature element. Cool, technical, American-modern.
   Palette : bg #f3f5f8 / ink #0f1622 / cobalt #2545c8
             low green #0e7a58 / high amber #b9760f
   Type    : Space Grotesk (display), IBM Plex Sans (body),
             JetBrains Mono (figures / ruler ticks)
