- sélecteur (pilule page vide, menu •••, commande /template), gestionnaire /templates, menu New ▾, From template, base inline dans un document

- 141 presets système (59 pages, 42 bases, 15 blocs, 25 lignes), titre auto depuis le template, variables title réservée

- récurrences RRULE + scheduler dédupliqué, agent apply_template/list_templates, API /api/templates + /api/v2/fd-templates

- correctifs : bouton Templates, centrage fenêtre, filtres CSP, flux de création, variable title

- tests : tests/test_fd_templates.py (19) et e2e/templates_picker.spec.js (8)

Inclut le travail déjà présent dans le working tree (vues Notion : view_query/view_aggregate/form_projection/geocoding, property_types, database_table, docs agents-skills) et ignore .playwright-mcp/.
