/* ---------------------------------------------------------------- report card
   The valuation reads like the dealer-desk cards the business already works from:
   one market level with the distances below it, the comparables as dots, and every
   correction named.

   No `color-mix()` anywhere below. It is unsupported in some of the browsers this form
   gets opened in, and an unsupported colour function does not degrade politely — the
   range band rendered as a solid black block and the ladder bars vanished entirely.
   Opacity on top of a token colour does the same job everywhere. */
