merge: PC5 embeds Insta col D Behold (round 1)

- scripts/build-carte-o.js : scan recursif AEP/Articles/, parse YAML + legacy header, extract wikilinks, infer 5 famille
- src/components/vue/CarteO.vue : D3 v7 force-directed avec drag, zoom + pan, click handler, tooltips, ResizeObserver
- src/components/vue/CarteOModal.vue : modal recap intention avec Teleport, Esc + backdrop close, transitions
- src/components/vue/CarteOWrapper.vue : fetch /data/carte-o.json, etat selectionne, fallback mobile (msg + miniature SVG)
- src/components/astro/ColCentre.astro : tabs Carte O / Chatbot, panneaux ARIA
- package.json : prebuild + predev hooks, build:carte-o script
- public/data/carte-o.json : 84 nodes / 94 edges sur 21 themes, distribution familles equilibree

Drill-down V1 = zoom + pan seul (V2 recursif backlog).
Pattern adapte de nav-carte/components/codev/CodevGraph.vue (sans coupling Nuxt).
Build Astro 6.3.1 OK, bundle CarteOWrapper 69KB.

+# Setup Behold pour embeds Insta
+
+Page cerveau col D (`ColInsta.astro`) consomme 2 feeds Insta via [Behold.so](https://behold.so) (gratuit, 2 feeds, sync 1h, sans login user).
+
+## Etapes
+
+1. Creer compte sur https://behold.so (gratuit jusqu'a 2 feeds)
+2. Connecter `@aep.politique` (Login Instagram via Facebook Business)
+3. Connecter `@julesneny` (idem)
+4. Recuperer les 2 feed IDs depuis le dashboard Behold
+5. Copier `.env.example` vers `.env.local` (a la racine du repo)
+6. Remplir `.env.local` :
+
+   ```bash
+   PUBLIC_BEHOLD_AEP=xxxxxxxxxxxx
+   PUBLIC_BEHOLD_JULESNENY=yyyyyyyyyyyy
+   ```
+
+7. Relancer `npm run dev` ou rebuild + redeploy (PC8)
+
+## Comportement par defaut
+
+Sans feed IDs valides (placeholder), le composant `InstaFeed.vue` affiche un fallback gracieux :
+- Titre du compte (lien direct vers Instagram)
+- Bio courte
+- Bouton "Voir sur Instagram"
+
+C'est OK pour un V1 visuel "complet". UX degradee mais pas casse.
+
+## Ressources techniques
+
+- API Behold : `https://feeds.behold.so/{feedId}` -> JSON array de posts
+- Sync : 1h (Behold rafraichit depuis Insta automatiquement)
+- CDN : images servies depuis Behold (pas de hot-link Insta direct)
+
+## CSP (PC8 deploy)
+
+Si une CSP est ajoutee au deploy Caddy, prevoir :
+
+```
+connect-src 'self' https://feeds.behold.so;
+img-src 'self' data: https://feeds.behold.so https://*.cdninstagram.com;
+```
+
+## Alternatives si Behold ne convient pas
+
+- **EmbedSocial** (~$8/mois) : https://embedsocial.com
+- **Scrape n8n nocturne** (V1.5) : Insta Graph API via compte Business + Page Facebook ; coherent avec PC6 journal-aggregate
+- **Posts manuels oEmbed** (V2) : Jules selectionne 6-10 URLs, oEmbed post-by-post
