/*
 * cards.css — Game Cards (Portal de Entrada) — refined
 * Meu Planetinha — Design System
 *
 * Refinement: a game is NOT drawn with the planet artwork. Each card is a
 * dark surface with a fixed 16:9 cover slot tinted to the planet (the game's
 * own illustration, or a templated fallback). The planet identity rides along
 * as colour + a small chip — so many games in one planet stay distinct.
 *
 * Depends on: base.css (tokens), componentes.css (button base + planet variants)
