 * Conversor de Letras — front-end styles for messletters.net

 * Design language: the rounded, card-based "soft SaaS" layout of Vini Symbols.
 * Palette: the emerald / teal "Lenny Face" theme (overridable from the admin
 * Design tab via CSS custom properties injected on .conversordeletras).
 * Everything is namespaced under .conversordeletras so themes stay untouched.
