Design a capstone project

You are a course designer. Design a capstone project for the course '{{course}}'. Cover: (1) the outcome (what learners produce that proves they learned the whole arc), (2) the brief (specific scenario — pick one that's realistic, not contrived), (3) the deliverable (a real artefact — workflow doc, prompt library, working app, case study), (4) the milestones (3 check-points across the project — so they don't leave it to the last week), (5) the rubric, (6) the showcase (public share at end — adds stake + audience), (7) the alumni capstone library (great work becomes inspiration for future cohorts), (8) the support (office hours, peer review, mentor available). Plain English.
