/* Base layout + design tokens — light, calm palette built around the real
   brand mark's exact teal (#00AB9F), RTL, Vazirmatn. Self-hosted fonts
   only, no Google Fonts CDN (see AGENTS.md "Lightweight/performance
   conventions").

   This replaces an earlier dark navy + amber palette that was designed
   before the real logo existed. The brand's own product promise is
   "peace for the household" — a dark, high-contrast tech palette fought
   that message, and it was never based on the actual logo color anyway.
   --accent carries the exact brand hex unmodified (logo, buttons, large
   fills); --accent-text is a deeper shade used wherever the color sits as
   *text* or a thin icon stroke on the light background, since the exact
   brand teal alone doesn't reach readable contrast there (~2.7:1) — see
   the accent-on-button vs accent-as-text distinction used throughout. */
