   GLASS theme — shield · steel blue
   ShieldAI — the privacy tool. A side project, and one of the five that expressed
   these ideas in a second vocabulary (--bg-elevated, --glass-border, --text-dim)
   this package replaces with the flagship grammar.

   Mark palette (the origin of every number below):
     #0A0D12 steel (ground) · #7CA6F7 highlight (accent) ·
     #4F8EF7 mid · #2557B0 shade (accent-2) · #E7EDF7 bone

   One blue family at three depths, deliberately: the mark is a shield plate and a
   single gradient should read as metal catching light, not as a rainbow. So the
   two accent hues here are 1.8 degrees apart, and the separation is carried by
   lightness — which is exactly what the ladder is for.

   Eight numbers. No structure. The lightness ladder, the radii, the type scale,
   the motion curve and the four state hues all come from src/tokens.css and are
   not visible from here — which is why a theme cannot break them.

     hue    taken from the mark, unchanged.
     chroma the mark's chroma, capped at the most saturated value sRGB can hold
            at the lightness the contrast law assigns. Two numbers per accent
            because the gamut at L 78% and the gamut at L 50% are different
            shapes; one number would mean silent clipping in one of the two.
     L      NOT HERE. Lightness is what contrast is made of, so it belongs to
            the system. See tokens.css §1.3-1.4.
