   TradingTrainer — Design tokens ("Desk" palette, D-038/T-080a)

   System" (tokens/colors.css, tokens/typography.css,

  /* ================= Belt-rank pass-state palette (T-084, D-046; supersedes D-045 X3) =================
     Fixed per-MODULE karate-belt colors (NOT a DAG-position ramp — a belt keeps its color
     regardless of ladder length/order). Each Built module key gets FOUR tokens:
       --belt-{key}-strap      / --belt-{key}-knot       — FULL hue, shown when Passed/TestedOut
       --belt-{key}-strap-soft / --belt-{key}-knot-soft   — LIGHT TINT of the same hue, shown when
                                                             in-progress (Unlocked/InProgress) or Locked
     Saturation encodes pass-state (D-046): earned progress reads at a glance without the old
     grayscale/opacity "Dim" treatment (dropped — Belt's Dim param now stays false at both /learn
     call sites). Reuses existing scale tokens (amber/green/blue/gray) where they fit; orange and
     brown have no existing scale, so their hex lives here (this token layer), per D-046. The
     breakout_followthrough "Black" belt is achromatic — its "soft" tint is necessarily a light gray
     (there is no non-gray light tint of black), unlike the other five hues.
     Palette (DAG order): daily_regime=Yellow · trend_range=Orange · sr=Green · transitions=Blue ·
     breakout_reversal=Brown · breakout_followthrough=Black. Consumed by the belt ladder (Learn.razor
     spine + card + card-strip) via Learn.razor.cs's BeltStrapVar/BeltKnotVar helpers, keyed on
     ModuleKey + IsEarned(State). Additive named tokens; extend as new-content epics flip Built. */
