/* =========================================================================
   main.css — Estilos públicos del comparador.

   Las variables `--theme-*` se inyectan en `<style id="theme-vars">` desde
   `src/views/layout.ejs` con los tokens resueltos del preset (cuaderno /
   ticker / patio) + overrides del admin. Aquí sólo declaramos defaults para
   que el sitio renderice incluso si esa inyección fallase, y aliases
   `--color-*` para compatibilidad con `admin.css` existente.

   Convenciones:
   - Densidad: `--theme-density-scale` modifica paddings clave (compact 0.92,
     normal 1, airy 1.08).
   - Acento decorativo: `[data-theme="cuaderno"]` añade textura papel,
     `[data-theme="ticker"]` rejilla y `[data-theme="patio"]` esquinas suaves.
   - Móvil-first; breakpoints en 640 / 720 / 980 / 1080px.
