   Reset, typography defaults, layout primitives.
   Reflects brand guide rules:
   - Display UPPERCASE / body sentence case / nav lowercase
   - Hard corners (radius 0–2px)
   - Borders + whitespace, never shadows
   - Backgrounds: paper / white / charcoal / black only
   - Red is accent, ≤10% of any composition */
