/* Школа „Просветители" — design system
   Direction: editorial (Gate 1 ALT Б, picked by Rusi) · palette derived from the new logo.
   Signature: the gold VECTOR ARROW, taken from Зорница's own whiteboard (the arrows over
   vectors in linear algebra). It encodes direction: 1 клас -> матура -> университет.
   It appears as ONE shape (never a shaft + a detached head), at three scales:
   the hero rule, the number-line axis, and the section eyebrow.
   Tokens audited: design/tmp/alt-b-editorial.css (design_token_audit.py exit 0). */
