/* StartSmart — Nocturne
   Ported from the app's Styling/DesignSystem.swift so the site and the app
   read as one product. Three rules carry it:
     1. One accent (#9184D9). success/warning/danger report state, never decorate.
     2. The accent is a line, an outline or a glow — never a fill.
     3. Every section opens the same way: uppercase overline, flush-left
        medium-weight title, hairline that fades to nothing at both edges.
   Nothing is centred and nothing is bold. Weight is not how this creates
   hierarchy. */
