- Add setup_sexp_bridge() and load_shared_components() to factory.py so all services get s-expression support automatically - Create shared/sexp/components.py with ~link-card component definition (replaces 5 per-service Jinja link_card.html templates) - Replace blog's link-card fragment handler to use sexp() instead of render_template() — first real s-expression rendered page content Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
