   kaloria.ai — shared UI layer (2026-10-10)
   Design: Anastasia Dremkova's Kaloria design system (kaloriaapp.hu, Sep 2026), ported to kaloria.ai.
   Type: Public Sans (display) · Instrument Sans (text) · Space Grotesk (labels, numbers) — all SIL OFL,
   self-hosted (Latin + Latin Extended). Non-Latin scripts use system faces (see :lang() blocks).
   NEVER ship the Dinamo display/text fonts from the design package: they are TRIAL licenses.

   This file is safe to add to ANY kaloria.ai page: it defines --kui-* tokens and .kui-* chrome
   (header, language menu, buttons, store badges, footer) and touches no global element styles.
   Page-level styles for the new templates live in home.css.
