/* Redmeres — design system (edition 05, 29 Sep 2026)
   Daylight site-office clarity: warm chalk ground, graphite ink, one Redmeres red used like a cut-in
   line — for action, emphasis and status, never as a wash. Archivo (slightly expanded) for display,
   Public Sans for reading. Motif: the programme grid (sites × months), used as an explanatory diagram.
   Components read role tokens (--bg, --fg, --line…) so the same markup works on chalk, white and graphite. */
