   Brand system v1.0 (locked).
   Tokens drawn directly from the Aspiture brand package:
   Soft Cream surface, Deep Maroon ink, Wordmark Maroon for
   headlines, Brass accent used sparingly (<5% of any view).
   Typography: DM Serif Display (headlines, italics, wordmark),
   Inter (body / UI), JetBrains Mono (labels, metadata, numerals).
