   Palette: Midnight #0A1128 · Deep Petrol #26505E · Amber Sand #E6B15E
            Aqua #4FD1C5 · Mist #8AA1A9 · Porcelain #EDF1F1 · White #FFFFFF
   Typeface: Poppins (fallback Helvetica Neue / Arial — never serif)
   Rule: the two accents (Amber + Aqua) together should never exceed
   roughly 10% of a surface. Amber = signal (CTAs, links, key data).
   Aqua = secondary accent, reserved for data series.
