/* ==========================================================================
   Intuitive Pathos — site stylesheet
   Zero dependencies, zero build step. Hand-authored.

   The color system encodes the product principle: Yang (warm) and Yin (cool)
   are always used at equal weight, never one as "good" and one as "bad".
   Elevated and suppressed are the same distance from a person's own baseline.

/* The reading is direct manipulation: the dashed line, the three intersection
   dots, the value pill and the pill's label must all sit at the same x on the
   same frame. Position must never be transitioned here, because CSS can only
   animate some of these parts: `cx` on a circle and `x` on a rect are
   animatable geometry properties, but `x1`/`x2` on a line and `x` on a <text>
   are not. Easing position therefore pulls the figure apart while it moves —
   the dots lag the line they are supposed to intersect, and the pill leaves
   its label behind, stranding paper-coloured text on the paper background so
   the reading appears to vanish mid-drag. Only colour eases. */
