   Logica del colore (validata con dataviz: contrasto ≥3:1 su superficie
   scura; verde↔rosso ΔE deutan 8,2 → SEMPRE codifica secondaria: segni
   +/−, triangoli ▲▼, testo nei badge — mai colore da solo):
   · verde/rosso  = SOLO polarità (su/giù, long/short, PnL) e stato LIVE/OFFLINE
   · ambra        = livello VPOC (stessa semantica della linea tratteggiata
                    nei grafici) e stato IDLE
   · inchiostri   = gerarchia text > dim > faint; i numeri portano il dato,
                    il colore porta il segno
   Forme: raggio 6 per chip/bottoni, 10 per card, 14 per dialog, pillole
   per stati e filtri. Spaziatura a passo 4px.                            */
