/* SHELEG Design — Prism token layer (an open-source infrastructure project's
   front door).
   Copy verbatim; consume only var(--…) in components.

   White passed through a prism: one static iridescent wash across the top of the
   page — pink to lilac to mint to cyan — under type that never picks up its hue.
   Body copy is MONO, which is what makes the page read as a project rather than
   a company. Below the wash the page is plain white.

   Extracted from https://milvus.io/ on 2026-08-09 by reading its live computed
   styles; ratios computed by importing test/validate_palette.py.

   Two corrections, in ACCENT and MOTION. */
