/* mira-site/explore/explore.css (arch-100). The explore family: shared
   header, fixture grammar, cards, legend, and footer for the public build
   tour. Colors, type and spacing come from ../tokens.css. This file adds
   ONE additive family of custom properties: the cool slate "example data /
   not checked" set (the arch-85 unverified palette), which the frozen
   token file does not carry. tokens.css itself is untouched.
   Family grammar, kept consistent with the main site:
     teal  = machine-checked (seals, measured math, primary actions)
     gold  = citations and document names
     amber = a person to talk to (the refusal-warmth family)
     slate = example data and unchecked guesses (dashed, hatched, square) */
