/* ==========================================================================
   Painel "Carreira" — três lentes sobre UMA régua de tempo.
   --------------------------------------------------------------------------
   Skills, experiência e timeline eram três painéis contando a mesma história
   (1999 → 2026) em recortes diferentes: por era de tecnologia, por cargo e por
   camada de stack. Aqui viram lentes do mesmo painel, e o que costura as três é
   a régua: cada item vira um segmento posicionado no tempo, então passar o
   mouse num cargo acende a era em que ele aconteceu e as camadas que estavam
   ativas naquele intervalo.

   Geometria: `--x` (esquerda, %) e `--w` (largura, %) são escritos pelo
   js/career.js a partir de `data-from`/`data-to` do próprio item — o HTML não
   repete número nenhum, e mudar um ano no template move o segmento sozinho.
