/* ════════════════════════════════════════════════════════════════════════════
   ERISEN — sistema visual do site institucional (redesign 23/09/2026)
   Direção: cinema + editorial + arquitetura + tecnologia silenciosa.

   Por que um arquivo só: antes cada página carregava 150–600 linhas de CSS inline,
   com os mesmos tokens redeclarados e divergindo (ouro numa, esmeralda noutra).
   Aqui ficam os TOKENS e os COMPONENTES; a composição é de cada página.
   Mesmos tokens, composições diferentes (Brief, regra 15).

   Dois universos, um sistema:
   · STUDIO  — escuro, fotográfico, serifa editorial. O que o mercado vê.
   · SYSTEMS — papel claro, grotesca + mono, linha técnica. O que organiza a operação.
   A troca de fundo (tema "papel") é o que separa os universos sem inventar cor nova.

   NÃO usar aqui: gradiente em texto, glow, neon, blob, partícula, glassmorphism.

/* ── FACES ────────────────────────────────────────────────────────────────────
   MONO: antes `--f-mono` era so uma pilha de sistema (ui-monospace, Cascadia
   Mono, SF Mono, Menlo, Consolas). Medido em 23/09/2026 com o CDP do Chromium:
   887 elementos e 10.717 glifos do site renderizavam em **Cascadia Mono**, a
   fonte do terminal do Windows — e mudariam de desenho em cada aparelho do
   visitante. A camada mono e a assinatura da marca aqui (claquete, ficha de
   case, etiqueta de setor, numero de etapa, rodape): tem de ser fonte servida.
   IBM Plex Mono e a mesma ja usada em erickantunes.com.br — um sistema
   tipografico para as duas casas. Peso 500 cobre ate 700 para nao haver
   negrito sintetico nos rotulos.

   SINAIS: os subsets 'latin' cobrem U+2191 ↑ e U+2193 ↓ mas NAO cobrem
   U+2192 →, U+2190 ←, U+2194 ↔, U+2197 ↗, U+21BA ↺, U+2713 ✓, U+25CB ○,
   U+25CF ● nem U+2715 ✕ — e os nove sao usados aqui como elemento de design.
   Sem esta face, 156 elementos caiam em Segoe UI Semibold e outros em Segoe UI
   / Segoe UI Symbol / Cambria Math / Consolas. Desenhada a partir da propria
   Instrument Sans (tools/build-marks-font.py): o que a familia ja tem sai dela,
   o que falta e a seta girada ou traco no mesmo peso. O unicode-range cobre so
   esses pontos: nenhum outro glifo do site e afetado. */

   · [data-m="mask"]  → revelação de projeto por recorte (clip-path)
   · [data-m="words"] → título entra palavra a palavra, por máscara
   · [data-m="fade"]  → texto de apoio: só opacidade, sem deslocamento
   · [data-m="rise"]  → bloco sobe pouco (reservado para linhas de lista)
   · [data-m="draw"]  → linhas de processo se desenham (via .is-in)
   Tudo só acontece com JS ativo (.js no <html>) e sem pedido de menos movimento. */

/* ── POLISH V3 (23/09/2026) — DEMONSTRAÇÕES E SINAL ───────────────────────
   A assinatura de motion da Erisen é SIGNAL / PIPELINE: uma linha de luz fria
   que atravessa a peça e muda o estado dela. Os três componentes abaixo são
   variações disso, e só isso:
   · .ba[data-scrub]  → a rolagem arrasta a linha do antes/depois (wireframe → render)
   · .seq             → uma linha de varredura troca o estado (humano → clone, dia → noite)
   · .sig             → um ponto percorre o fluxo e acende cada estação (Systems)
   Sem JS: tudo aparece estático e legível. Menos movimento: nada anda sozinho. */
