/* Renso — refined palette, MOBILE-FIRST.
   Base rules (no media query) are the small-screen layout: single-column
   stacks, a wrapping nav, and type that fits a 320px phone. Two
   `@media (min-width: …)` blocks at the very end progressively restore the
   tablet and the original 1440px desktop artboard verbatim, so desktop is
   unchanged while phones get a first-class layout.
   Inspiration: x.ai (quiet, ultra-minimal, generous space, hairline
   rules, large restrained type) + Robinhood (confident product density,
   clean data panels). Shared tokens, per-artboard overrides via
   [data-variant]. */
