/* ============================================================================
   Cabecalho — a folha partilhada entre a homepage e as paginas do servidor
   ============================================================================
   GERADA a partir do <style> do index.html por scripts/gerar_header_css.py,
   para o aspeto ser exactamente o mesmo em todo o lado. Se mexeres no
   cabecalho da homepage, corre o script outra vez.

   O filtro e pelas classes que o markup do cabecalho usa de facto: a
   primeira versao filtrava por uma lista escrita a mao e deixou de fora o
   ".nav-links", o que punha o burger no ecra grande e o menu em lado nenhum.

   Os @media entram tambem: e neles que vive a troca entre menu e burger.

   As variaveis vao em :where(:root), que tem especificidade ZERO: na
   homepage as dela ganham, nas outras paginas estas servem de rede. */
/* A homepage resolve isto no reset global dela (* e ul), que o filtro por
   classes nao apanha: sem estas tres linhas as <ul> do menu voltam ao
   "disc" e aparecem pontos entre os itens. Fica preso ao cabecalho, para
   nao apagar os pontos das listas do conteudo das paginas. */
