   LeaWin — Learning & Winning
   Design tokens
   Palette:  --ink (deep indigo, headlines/nav) · --gold (amber, "winning" accent)
             --paper (warm parchment bg) · --teal (secondary/success)
             --charcoal (body text) · --mist (hairline borders)
   Type:     display = Fraunces (falls back to Georgia) — used sparingly, large sizes only
             body    = Work Sans (falls back to system sans)
             utility = JetBrains Mono (falls back to ui-monospace) — prices, counts, labels
   Signature: the "win-ladder" — ascending step bars used in the hero and beside plan names,
              standing in for progress/achievement without leaning on cliché badges.
