   Help Panel — design system  (muriel redesign, 2026-06-26)
   ----------------------------------------------------------------------------
   The in-app brand is neon-green PHOSPHOR (brand-tokens.css / docs/STYLE_GUIDE.md
   — "do NOT cross" palettes). The green was never the problem: the accreted
   Tailwind sky/slate (#7dd3fc, #cbd5e1, #94a3b8) was the off-brand intruder.
   This file evicts it, binds every role to the canonical --pd-* tokens, and
   adds a polish pass. Loaded AFTER styles.css / shared-ui.css so its
   #selector.help-active-scoped rules win over the older scattered .help-* rules
   (left in place, now superseded).

   CONTRAST (polish.md rule 17): the panel stays glassy, but every text-bearing
   surface is a near-opaque CARD scrim, so text holds >=8:1 over ANY fractal
   frame rather than depending on what shows through — not a panel-wide plate.
   Audited vs a card over a bright fractal patch: label #aaffaa 14.6, body
   #f0f0f0 15.3, dim #cfe8cf 13.4, muted #c8c8d0 10.5, accent rgb(var(--pd-accent-rgb)) 12.7,
   dark-on-phosphor 13.9. (Emerald --pd-active is FILL-only — 7.8:1 as text.)
