  ONE STYLESHEET, NO INLINE STYLES / UNE FEUILLE, AUCUN STYLE EN LIGNE
    Every page links this file and carries no <style> block or style=""
    attribute, which is what lets `_headers` hold the CSP at `style-src 'self'`.
    Chaque page lie ce fichier, sans bloc <style> ni attribut style="", ce qui
    permet à la CSP de rester à `style-src 'self'`.

  THE LOOK / L'ALLURE
    A proudly Canadian nameplate: the double name set large in Gloock, the
    hyphen drawn as a red bar, a woven selvedge along the top edge in the
    colours of the Maple Leaf tartan (Canada's national tartan), an "Elbows Up!"
    pennant, and a silhouette scene of a moose, a Mountie beside the flag, a
    beaver and Canada geese. Dark ink by default, warm paper in light mode.
    Une plaque fièrement canadienne : le double nom en grand, le trait d'union
    en barre rouge, une lisière aux couleurs du tartan Feuille d'érable (tartan
    national du Canada), un fanion « Elbows Up! » et une scène en silhouette.
