/* ==========================================================================
   MODULES — a slot-together grid for a personal site
   --------------------------------------------------------------------------
   One stylesheet, shared by every page. Change it here, every page follows.

   The whole system in one breath:
     <main class="board">        a 5-column grid (3 on tablets, 2 on phones)
       <section class="m">       a module: one cell, 233px tall minimum
       class="m w2 / w3 / w4"    span 2, 3 or 4 columns
       class="m full"            span the full width
       class="m tall"            span 2 rows
       class="m signal"          accent fill
       class="m dark"            black fill
       class="m slot"            grey image placeholder
       class="m photo"           an <img> that fills the module
       class="m ghost"           an empty, outlined cell (decor for sparse pages)
       <article class="m prose"> plain HTML for long writing — no classes inside

   Fonts load from Google Fonts in each page's <head>. To self-host later,
   swap that <link> for @font-face rules here; the names below stay the same.
