/* ============================================================
   Renterra — platform brand design system
   Renterra is the resold white-label SaaS (a SEPARATE brand from
   any tenant storefront like Havana). This theme is intentionally
   distinct: cool "ink + teal" SaaS look, Space Grotesk / Inter.
   Everything is CSS-variable driven — re-theme by editing :root.
   PROVISIONAL identity: easy to swap when a final brand is set.
