/* Contorno traçado como um percurso único: o triângulo externo primeiro, depois
   o A e os dois T, um de cada vez. Ao fechar a última forma tudo dissolve e a
   marca descansa até o ciclo recomeçar.

   A ilusão de "uma linha só" depende de duas coisas:

   1. Velocidade constante da caneta — 2141,7 unidades/s, de onde saem as
      janelas de tempo abaixo. Cada forma leva o tempo proporcional ao seu
      próprio comprimento, e nenhuma corre mais que a outra.
   2. Easing LINEAR, obrigatoriamente. Com curva de aceleração a caneta
      desaceleraria no fim de cada forma e arrancaria de novo na seguinte,
      expondo as emendas.

   O ciclo é de 14,6s: 3s de desenho, 0,3s com o contorno completo em tela, 0,1s
   de dissolução, 1,2s de reflexo e 10s de repouso. Todos os paths compartilham
   essa duração e diferem apenas nas porcentagens, o que os mantém em fase sem
   depender de animation-delay:

     forma        compr.    janela             keyframes
     triângulo    3000,0    0,000s a 1,401s    0%       a  9,596%
     A            1159,5    1,401s a 1,942s    9,596%   a 13,301%
     T esquerdo   1132,8    1,942s a 2,471s   13,301%   a 16,925%
     T direito    1132,8    2,471s a 3,000s   16,925%   a 20,548%
     completo               3,000s a 3,300s   20,548%   a 22,603%
     dissolve               3,300s a 3,400s   22,603%   a 23,288%
     reflexo                3,400s a 4,600s   23,288%   a 31,507%
     repouso                4,600s a 14,600s  31,507%   a 100%

   As porcentagens são relativas à duração: ao mexer nos 14,6s, todas mudam de
   significado e precisam ser recalculadas.

   Cada dasharray é o comprimento da própria forma com ~10 de folga, para o
   traço fechar sem deixar sobra no ponto de emenda. Remedir se a arte mudar. */

   Ciclo de 2,1s com 3 ecos por lado defasados de 0,7s: um pulso nasce a cada
   0,7s e o último se apaga quando o quarto nasceria, então a emissão é contínua
   e sem costura visível. Os delays são negativos para a propagação já estar em
   curso no primeiro quadro — sem eles a tela ficaria 1,4s com o núcleo sozinho,
   justamente no instante em que o overlay aparece.

/* --- Brilho dos blocos cumpridos (planner semanal) ---
   Marcação em templates/planejamentos/_calendario.html.

   Três estrelas de 4 pontas cintilando no canto inferior direito do card, em
   sequência, como um ponto de luz que pisca. Cada uma fica visível ~0,6s num
   ciclo de 3,6s: o card passa a maior parte do tempo parado, senão sete colunas
   de blocos cumpridos viram um pisca-pisca.

   A estrela é branca, mas o card cumprido é verde-claro (bg-emerald-50/60) —
   branco sobre isso não apareceria sozinho. Quem desenha a forma é o
   drop-shadow esmeralda: o halo escuro recorta o núcleo branco e o conjunto lê
   como um reflexo pontual.

   Os cards são dessincronizados por --brilho-fase, calculada no template a
   partir do índice do dia e do bloco. Sem ela as sete colunas piscariam no
   mesmo quadro, o que denuncia a animação como enfeite. */
