feat: crimson CTA accents, white surfaces, Zeitung font, diagonal dividers

- Add --color-accent-fill (#cc0230) / -hover / -ink tokens; repoint all
  solid yellow "button" surfaces (Button accent, IconButton accent,
  language-selector active pill, Navbar cart CTA, Kaiserhacks chip,
  accent Badge) to crimson fill + white ink. Yellow --color-accent kept
  for functional text accents.
- Secondary button: transparent fill, white border, white text/icons,
  translucent-white hover (no longer mimics the primary default).
- Surfaces to pure white: --color-cream and --color-surface -> #ffffff
  (cream-toned logo follows via text-cream); theme-color -> #ffffff.
- Self-host Zeitung (Regular/Bold woff2, mirrored from production);
  point --font-sans/--font-serif at Zeitung; drop Google Fonts CDN.
- Remove yellow highlighting on hero/title emphasis and hero eyebrows
  (text-accent-soft -> text-cream, eyebrows -> text-cream/75).
- WaveDivider + homepage section dividers: straight diagonal (low-left,
  high-right) at double height for ~2x the right-to-left difference.
