/* =============================================================================
   Glyph — one stylesheet, two skins.

   A page declares which it wants on <html data-skin="paper"> or "board".

     paper  reading rooms: the landing page, writer profiles, submissions, about.
            Warm ground, serif at a real reading size, a single oxblood accent.
            Light-first, with a dark variant for anyone whose system asks.

     board  data rooms: the calendar. Inherits the datarail.org palette on
            purpose, so the family resemblance to /events is visible. Dark only —
            a board is a board.

   The split is the argument: writing is data, and the two deserve different
   rooms. Everything structural is shared so the two never drift apart.
