    White ground, near-black monospace body, and one accent: Signal Yellow.
    The signature is the RGB chromatic split on display type — a yellow glyph
    with a pure-red copy behind it one way and a pure-cyan copy the other,
    the way a misconverged CRT tears a character apart.

    Yellow #FFD21F is 1.5:1 on white. It is an accent for DARK grounds, for
    fills, and for the glitch stack — never functional text on white. Ink
    carries every text-weight accent. This is the one rule the palette
    depends on.                                                             */
