   Light parchment, sepia ink, deep red-brown accents — kept LIGHT and texture-free so it prints well and stays sharp on phones.
   Every text colour below is checked by "tl.py qa" (WCAG contrast ≥ 4.5 : 1 on the paper / panel, ≥ 4.5 : 1 for light text on
   the day colours). Colour is never the only signal: Gospels are also labelled (Matt, Mark …), days are named.
