/* Metre2 Compress PDF 1.0 - "the press" (2026-10-29).
   Accent: violet #b46cff -> pink #ff6fae, chosen to sit well away from the portfolio's existing
   accents (PDF Flatten lime, the shell's teal, the many blues). Icon rail + file shelf + control
   deck with a size gauge - a different shape from PDF Flatten's three-column light table. */
