feat(marketing): PAS frame sections (Problème + Solution) after trust bar

- Problème section (light bg-brand-bg, white cards): 3 risk cards
  (Cloud Act, Loi 25 biométrie art. 60.1 LPRPSP, sanctions disciplinaires
  9 ordres pros). H2 grad-text accent on 'violent la Loi 25' — defensible
  legal claim citing CAI + LPRPSP statutes by name. text-brand-navy/70 for
  all body text (WCAG AA compliant, no /40 or /50 regression).
- Solution section (bg-brand-navy with single subtle green orb): 3 pillars
  (100% local, Conforme Loi 25, Précision FR-CA). H2 grad-text accent on
  'par design'. Pillars cite specific tech (WhisperX Large-v3, Mistral 7B,
  pyannote, OVH Beauharnois, AGPL v3) — all factually verifiable.
- French typography: NBSP via   + |safe before %, $, and within
  'Loi 25' to prevent line break separation (OQLF rule).
- 4 new tests verify both sections, 3 cards each, key tech mentions,
  and WCAG-safe opacity policy.
