/* ══════════════════════════════════════════════════════════════
   A MINHA BIBLIOTECA — estante de capas + leitor

   Princípios (os mesmos do resto do SOMOS, ver index.html):
   · uma acção principal por contexto — aqui é "Adicionar livro";
   · a informação aparece quando é precisa, não toda ao mesmo tempo:
     as acções de cada livro só surgem no hover/foco;
   · cartões todos do mesmo tamanho, alinhados numa grelha rígida;
   · sem molduras a competir — a capa é que manda;
   · animações curtas e só onde explicam alguma coisa.

   Usa os tokens do tema (--purple, --card, --border…), por isso a
   personalização de cores da criança continua a funcionar.
