   Becoming HealthyHer — design system
   Fresh-but-related to the personal site: a calmer, more institutional
   warm palette + a new type system.
   Type:   Newsreader (display serif) · Hanken Grotesk (body + labels)
   Palette: warm linen paper, deep aubergine/mauve primary, dusty-rose
            connective accent, restrained gold reserved for credibility.
   Mood:   trustworthy / clinical-credible + calm / reassuring.
   Live tweaks: density, accent hue set, display + body fonts.
