feat(marketing): A-2.7b témoignages placeholder + FAQ accordion + CTA + JSON-LD
- Pre-launch testimonials section: 3 placeholder cards (avocat, CPA, municipal)
with persona icons + 'Témoignage à venir' label — NO fabricated quotes
(LPC art. 219). Expected publication mai-juin 2026 from T-4.1 interviews.
- FAQ accordion: 7 verifiable Q&A using Alpine.js core (x-data + x-show +
built-in x-transition; NO x-collapse plugin). Each item has @click toggle,
:aria-expanded, aria-controls, role="region" panel, focusable button.
- Schema.org FAQPage JSON-LD inline at end of FAQ section — striptags +
replace(' ', ' ') to normalize entities for Google FAQ rich result.
- CTA final: 'Réservez votre pré-inscription' (mailto + #tarifs anchor),
cosmic orbs to mirror Hero (page closure), ghost variant secondary button.
- Inline TESTIMONIALS and FAQ Python lists in src/marketing/routes.py
(no PyYAML dep — YAGNI; T-4.1 can introduce it when real data warrants).
- 8 new tests covering testimonials placeholders, forbidden fake names,
7 FAQ panels, Alpine bindings, JSON-LD schema, CTA wording, route data.
