/* TA-Decor webfonts.
   NOTE (font substitution): the logo wordmark uses a bespoke techno display face
   that is not distributed. We pair Google Fonts that carry full Vietnamese
   diacritics and match the brand's strong-geometric / clean-readable intent:
   - Sora        → display / headings (geometric, confident, luxury-tech feel)
   - Be Vietnam Pro → body & UI (designed for Vietnamese, highly readable)
   If you have the original licensed display face, drop the files here and
   replace these @import lines with local @font-face rules. */
