/* @aiherway/shared/tokens-spa.css
 * The AI Her Way "spa" design system. Calm, warm, editorial-soft.
 * A drop-in alternate to tokens.css — same variable names and class API,
 * so a page switches aesthetic by swapping this one <link>.
 *
 * Direction: coconut base (warm creamy off-white), duck-egg hairlines
 * (pale blue-green), Nexa body, Noto Serif Display headings. Thin 1px
 * hairlines, soft radius, generous whitespace, gentle shadows.
 * Australian English. Heritage palette (charcoal/forest/clay) kept as text
 * and deep accents so it still reads as AI Her Way.
