Start by documenting the current sharing process and reviewing the linked staging deck, including slide 3360. Propose the redesigned process and modal changes in an issue comment, then gather product and developer feedback. Done means the process is finalized, before-and-after images are added to the staging slide, and stakeholder sign-off is recorded.
