 * CRIE.LEARNINGLINES.SHELL.01
 * Camada compartilhada para a entrada pública e privada de Linhas de Aprendizagem.
 *
 * Princípios técnicos:
 * 1. Progressive enhancement. A página permanece funcional sem JavaScript.
 * 2. Container queries para composição local, sem acoplamento ao viewport inteiro.
 * 3. content-visibility para reduzir trabalho de renderização abaixo da dobra.
 * 4. Movimento opcional e respeitando prefers-reduced-motion.
 * 5. A Linha é um percurso geral. No contexto universitário, ela é a disciplina canônica.
