/* =========================================================
   llm.css   o design system da SÉRIE DIDÁTICA

   ATENÇÃO ao nome do arquivo: ele nasceu para llm.html, mas
   hoje é a base visual de TODAS as páginas da série. O nome
   ficou por causa de cache: renomear invalida o arquivo para
   quem já visitou o site, e não compra nada em troca.

   Camada 1 de 3 da série:
     styles.css   tokens globais do site (mono, branco, verde)
     llm.css      ESTE arquivo   tokens de etapa + .llm-*
     didatica.css componentes compartilhados (.emb-*, .dd-*)
     <pagina>.css o que só existe numa página

   O que mora aqui: as variáveis --c-* / --hair* / --ink-*, o
   esqueleto (.llm-shell, .llm-aside, .llm-main, .llm-stage),
   a navegação, e os componentes de conteúdo (.llm-panel,
   .llm-card, .llm-note, .llm-bar, .llm-grid, .llm-formula…).

   REGRA DE ALTERAÇÃO: mudar qualquer seletor .llm-* ou
   qualquer variável do :root abaixo afeta todas as páginas da
   série de uma vez. Se a mudança serve a uma página só, ela
   pertence ao CSS daquela página   não a este arquivo.
   Adicionar seletor novo é seguro; alterar ou remover exige
   revisar a série inteira.
