   THE PURPLE RULES — the whole look depends on these three:
     1. SATURATED VIOLET IS LIGHT, NOT PAINT. It appears as glow, hairline and
        small text — never as a large filled block. A big #8B5CF6 panel is
        exactly what makes a purple site look like a free template.
     2. VIOLET TEXT ON DARK IS --lilac, NEVER --violet. #8B5CF6 on #08060F is
        ~4.0:1 and fails WCAG AA. #C4B5FD passes comfortably.
     3. ONE WARM ACCENT. Gold appears on the availability dot and nowhere else,
        so the palette isn't monochromatically cold.
