/* ==========================================================================
   Interim Growth OÜ — Stylesheet

   VISUAL DIRECTION: «Growth panel»
   - Nordic-Baltic functional design: luminous, precise, no darkness, no neon.
   - Base: cold white and ice grey. Accent: a sober corporate blue in the
     enterprise-trust register (HP reference), never saturated or electric.
     A lighter blue works as the secondary signal.
     Deliberately far from Noelander's turquoise and Hydra's red.
   - Modular card grid, like a control panel, with an ascending diagonal as
     the reading axis.
   - Mobile-first: everything defined for 390 px first.
