patch_render_engine_c4.py — Chantier C4 (Assets & images)
=========================================================
Patch strict de render_engine_v2.py :
P1. _image_size() module-level : dimensions via Pillow, sinon
mini-parseur d'en-têtes PNG/JPEG (aucune dépendance).
P2. Composants : _asset() (résolution dans assets/ du projet),
_image() (insertion cover = recadrage centré symétrique, jamais de
déformation ; contain = letterbox centré), _rect_alpha() (voile de
couleur avec transparence OOXML), et les renderers
_render_image_split (image 40 %, side left/right, légende sur
bandeau navy) et _render_image_full (plein cadre + voile navy
60 % + titre display blanc).
Image introuvable → placeholder card_alt + nom du fichier
(warning console), jamais de crash.
P3. Freeform : nouveau bloc {type: image, image: fichier, fit:}.
P4. REGISTRY : image_split, image_full.
P5. CLI : --assets (défaut : <dossier du yaml>/../assets, soit
projets/<slug>/assets/ dans le flux facilitator — aucun patch
facilitator nécessaire pour le rendu).
Usage (dossier du pipeline, single-line) :
python3 patch_render_engine_c4.py
Indépendant du patch C3 (ancres distinctes, tout ordre). Vérifie chaque
ancre, écrit .bak-c4, compile, idempotent.
