Notification Cascade editing contract

Surface ownership

This is a generic notification presentation with a HyperFrames-branded payoff. The notification geometry, backdrop, stacking behavior, typography, and motion belong to the template. The supplied website is the subject brand placed into declared slots.

Editable slots

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

  • notifTitle, message1 through message4, and appName
  • headlineTop, headlineAccent, and footerText
  • brandLogo, using a transparent mark that remains legible on the dark closing card

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

Do not change CSS, layout, backdrop, notification chrome, scene structure, duration, timing, easing, stacking, or reveal behavior. Do not replace any image outside the declared closing-card logo slot. Colors are protected because this template declares no color variables.
