perf(movimento): sem tela vazia, passagens em CSS e vitrine leve

Browse Source 
Projetos sobem sobre o palco do hero e o celular tem hero de uma tela sem mergulho; passagens com animation-timeline em CSS, sem GSAP nem motion; troca da vitrine sem texto duplicado; moldura de celular só com pôster e scrub reencodado em 960 px (9,4 para 5,2 MB); 3D monta na primeira interação e para quando parado; transição entre páginas do mesmo segmento; foco em anel duplo; texto de 15 px no celular; código morto removido.

* Rolagem como um vídeo: o GSAP liga cada passagem de uma cena para a seguinte à posição da rolagem (rolar
* para cima volta o "vídeo") e, no mouse, o Lenis suaviza a roda.
* Rolagem da home. Duas coisas, nenhuma delas com biblioteca de animação:
*
* Uma única passagem para a home inteira, só com opacidade e um deslocamento vertical curto:
* - a cena que entra chega com fade e sobe ENTER_OFFSET px até o lugar dela;
* - a cena que sai some com fade e termina SEMPRE em opacidade 0 (nenhuma cena anterior fica "fantasma" atrás
* das seguintes);
* - nada de recorte (clip-path), escala ou rotação, e nenhuma cena é escondida com visibility: o conteúdo
* nasce visível no HTML do servidor e a opacidade só muda por rolagem (Ctrl+F e leitores de tela enxergam
* tudo, e sem JavaScript tudo aparece).
* As cenas ficam no fluxo normal da página, uma depois da outra. A única rolagem "presa" é a do CSS: o hero
* (sticky) e a vitrine de projetos (sticky); este arquivo não prende nada.
* 1. As passagens entre cenas são CSS (globals.css, `animation-timeline: view()`): o conteúdo de cada seção
* (`.ds-section-shell`) chega com fade e uma subida curta enquanto a seção entra na janela, e o fundo da
* seção fica sempre inteiro (seções do mesmo tom não piscam em cinza). Nada de JavaScript por quadro, e onde
* o navegador não tem o recurso o conteúdo simplesmente já está lá. Qualquer filho direto de <main> é uma
* cena; nada aqui depende de uma seção específica existir.
* 2. Este hook cuida só do que o CSS não faz: no mouse, o Lenis suaviza a roda (com o relógio ligado apenas
* enquanto algo se move, nunca com a página parada), e os links internos (#id) "avançam o vídeo" até o
* destino em vez de saltar. No toque a rolagem nativa corre em outra thread: nem o Lenis é baixado.
*
* Cada cena tem uma entrada e uma saída, cada uma com o próprio gatilho, e a saída só começa depois que a
* entrada da mesma cena terminou (cenas curtas não brigam pela mesma opacidade). Qualquer filho direto de
* <main> é uma cena; nada aqui depende de uma seção específica existir.
* As únicas rolagens "presas" são as do CSS: o hero (sticky) e a vitrine de projetos (sticky).
