/* theme.css — Dialogue 2.0 design system.
 *
 * Pico CSS (vendor/pico.min.css) supplies consistent component defaults; this file
 * bends Pico to ONE calm, editorial identity and defines the shared chrome (header,
 * identity bar, cards, buttons, fields, tabs, toast) so every page reads the same.
 *
 * Aesthetic: a warm paper ground, generous air, a single confident teal accent
 * (amber used sparingly), Fraunces for display, DM Sans for body, DM Mono for meta.
 * De-stressed = hairline borders over boxes, whitespace over shadows, one accent.
 *
 * Load order in every page:  fonts  →  pico.min.css  →  theme.css
