  /* Color — Ink + Electric brand palette (logo package), replacing the retired
     navy/coral identity. Two token families that look similar but mean
     different things — keep them separate:

     --color-ink / -secondary / -tertiary: default TEXT colors. These flip
     under prefers-color-scheme (see below) — dark text in light mode,
     light text in dark mode.

     --color-brand-dark: the literal brand Ink (#0B0B12) used as a SURFACE —
     primary buttons, hero/nav bands, the admin sidebar. Deliberately never
     flips with theme: it's already dark, so it renders identically and
     correctly regardless of light/dark mode. Mixing this up with
     --color-ink would make every primary button and dark band invert to a
     near-white surface under dark mode — don't.

     --color-electric is the single accent (#3D5AFE). It clears AA on both
     white and as a white-on-electric button fill (~5.1:1 either direction)
     — see https://www.w3.org/TR/WCAG21/#contrast-minimum. It does NOT clear
     AA for small text sitting on --color-brand-dark (~3.8:1) — on dark
     surfaces use --color-electric-tint for text/links instead, and keep
     plain --color-electric for large elements, icons, and buttons that
     carry white text rather than colored text. */
