   MinerOS Hub — Panel de cobros (membresía · Telegram · checkout)
   Esta es la pantalla donde entra el dinero: manda la claridad, no el
   adorno. Tres decisiones de fondo:
     · una sola columna de lectura en móvil y dos en escritorio, con el
       checkout siempre a la derecha (donde cae la vista al final)
     · sin emoji del sistema: los símbolos son SVG o glifos tipográficos
       (₿, ₮), que respetan la tipografía y no cambian según el teléfono
     · toda animación es discreta y se apaga con prefers-reduced-motion;
       en una pantalla de pago, el movimiento debe tranquilizar, no distraer
