/* Lunai — sistema de temas (decisão de Leonardo, 23/10/2026, sobre a fase 1
   em files/lunai-polish/): DUAS direções aprovadas com alternador, no mesmo
   padrão do Orai — os componentes são únicos e só as VARIÁVEIS mudam.

   Tema PADRÃO = Direção A "Noite Lunar" (dark premium): noite profunda,
   prata luar e o acento Violeta Aurora — ponto médio do degradê neon do
   brand kit dele (files/brand-kit-lunai: azul #38B6FF → rosa #FF4FD8).
   Tema ALTERNATIVO = Direção B "Estúdio Claro", via [data-theme="estudio"]
   no <html>: branco luar, prata escovado, tinta noite, o MESMO violeta
   (textos de acento no tom profundo, por contraste).

   O dourado do kit saiu de primária (colidia com o Orai, da mesma conta) e
   fica como legado da marca em capas/animações. O wordmark do cabeçalho é a
   ARTE REAL do brand kit recolorida por tema (logo-lunai-noite.png /
   logo-lunai-estudio.png) + a lua crescente violeta — o gancho do nome. */
