/* ==========================================================================
   AJ3 Cool-Aire 2026
   Design system. Single-hue heat scale.

   There is no second colour in this system. Every value is the AJ3 logo
   orange moved along one axis: driven down to a warm near-black for panels,
   up through burnt amber and the brand orange itself, out to a pale warm
   highlight. Neutrals are warmed to match rather than left cool grey, so
   nothing on the page reads as blue.
   ========================================================================== */

/* --- 1. TOKENS ----------------------------------------------------------
   The orange is sampled from the AJ3 logo itself: the saturated core of the
   wordmark sits at hsl(24 95% 62%), which is --t7 below. Every warm value in
   the ramp is derived from it rather than picked by eye.
   Light is the default scheme. Dark is opt-in via [data-theme="dark"].       */
