    October 2026

    Loaded after css/styles.css by the syllabus and schedule pages only
    (010/010hsyllabus.html, 010/010hschedule.html, and the matching pages
    in 005b/inperson, 005b/hybrid, 055/inperson, 055/online).
    Everything is scoped to .syllabus so no other page is affected.

    Canvas strips stylesheets on paste; the HTML inside
    <article id="syllabus"> is fully readable without this file.
