   Buyer simulator (#/simulator) — views/simulator.js
   -----------------------------------------------------------------------------
   Moved here from the customer app when the simulator became a tool for the
   coach and staff (2026-10-22). Tokens only: every colour is a var() from
   admin.css, or a color-mix() of two of them. admin.css's palette is the
   customer palette (test_theme_drift.py keeps them equal), so the pairings
   this relies on are the ones already in PAIRS in test_theme_contrast.py:
   --ink / --ink-soft / --ink-faded on the light surfaces, --ink / --ink-soft
   on the tints, and each -deep ink on its own -soft tint. Nothing here sets
   text in a bright token.

   The 1–5 reaction scale is DIVERGING, not sequential: 1–2 lean away, 3 is
   neutral, 4–5 lean toward. Two hues (amber away, violet toward) and a grey
   midpoint, with matching lightness per arm (OKLab L ≈ .53 / .69 / .82 / .71 /
   .53) so neither side looks louder than the other. The grey midpoint is only
   1.7:1 on the card, so it never carries meaning alone: there is always a
   legend, a 2px surface gap between segments, a per-segment title and an
   aria-label in words.
