Share-Sheet Carousel editing contract

Surface ownership

This template depicts an operating-system share sheet. The supplied website is the item or sender shown inside that interface; it does not own the surrounding system UI.

Editable slots

Only defaults declared in data-composition-variables are editable:

• shareTitle, senderName, itemLabel, and stripText
• acceptLabel and declineLabel
• slideImage1 through slideImage4; each image also drives its matching blurred background
• brandLogo, using a transparent horizontal wordmark

Keep replacement copy within 20% of the original length.

Safe editing mechanics

Call set_template_variable_defaults once with the existing variable ids and their new defaults. Do not directly edit or rewrite index.html or its data-composition-variables attribute; the imported declaration is HTML-entity-encoded JSON and the setter preserves that encoding. Never edit __template_baseline__.html or a duplicate composition file. For an image slot, pass only the token returned by an image tool. Validate after the setter succeeds.

Protected

Preserve the share-sheet palette, typography, buttons, geometry, carousel layout, scene structure, duration, timing, easing, and tap animation. Do not replace any image outside the declared slide and logo slots, and do not recolor the operating-system interface.
