Canvas Sprint 4: rsvp_resource_loan_section option recipe

Deliver the resource loan/checkout section as an opt-in Canvas recipe. Not included in rsvp_community_landing by default — sites apply this recipe explicitly when they have a loan or checkout workflow.

Scope

• New recipe: rsvp_resource_loan_section in rsvp-recipes/recipes/
• Canvas block showing loan/checkout availability and action for a given resource
• Integrates with reservation workflow (ADR-0017) — not a separate booking system
• Designed for resources that are loaned (equipment, rooms, tools) vs. reserved time slots

Design questions to resolve before building

• Is "loan" a status on the reservation entity, or a separate field on rsvp_resource?
• What's the return/due-date model — SmartDate range on the reservation?
• Who can initiate a loan checkout — member only, or coordinator-approved?

Definition of Done

• rsvp_resource_loan_section recipe applies cleanly on a site with rsvp_community_landing active
• Loan block visible in Canvas editor on resource pages
• Checkout action creates a reservation node in the loan state
• Recipe documented with prerequisites and opt-in instructions

ADR: ADR-0031
Depends on: ADR-0017 (resource reservation architecture)
