/* Antitotem — Objeto Sonoro — identidade própria do instrumento.
   Paleta extraída do app real (src/app/Main.cpp, namespace material):
   fundo quase-preto, âmbar/madeira como acento primário, vermelho como
   acento raro de estado/aviso. Não compartilha a paleta do portal geral
   RASGO (RASGO_WEBSITE/styles.css) por design — cada instrumento mantém
   identidade visual própria (ver GOVERNANCA_E_TRANSVERSALIDADE.md §10). */
/* Self-hosted, not named-system-font (RASGO sites rule, 26 ago. 2026):
   "DejaVu Sans"/"DejaVu Sans Mono" are free (Bitstream Vera-derived) but
   were only ever named here, never embedded - common on Linux, rarely
   pre-installed on Windows/macOS, so the site rendered in a different
   generic fallback font depending on the visitor's OS (same bug found live
   on the Navalha 2 site the same day). Subset to Latin + common punctuation/
   arrows actually used on this site. */
