{#- Course-structure figure, driven by `criteria.course` in data/criteria.yaml.
    Phases tile weeks 1..total_weeks left→right; each phase's share of the
    width is its `weeks` span, so you can rebalance the course without
    touching the SVG. Assessment markers (point or span) are positioned by
    week number so they always line up with the band beneath them. -#}
