     * hexes (a bare string/`Color::hex()` runs the value through
     * `Color::generatePalette()`, which discards its lightness and maps a
     * fixed per-shade lightness/chroma table instead — see MAN-118 survey).
     * Shade 600 pins `#556B2F` (Oliva Herança) and shade 700 pins `#3E5219`
     * (Oliva Profundo). `Filament\Support\View\Components\ColorMaps\
     * ButtonComponentColorMap` was used to verify empirically (not assumed)
     * that a solid primary button resolves to `bg: 600, hover:bg: 500, text:
     * 50` at 5.42:1 / 4.57:1 contrast (WCAG AA). Shade 50 is a pale olive
     * tint rather than pure white deliberately: `BadgeComponent`/
     * `badge.css` apply `bg-color-50` directly as a badge's background
     * (independent of the button map above), and a pure-white 50 would
     * render a "primary" badge as an all-but-invisible pill against the
     * Papel Marfim (`#FBF9F4`) panel body.
