/* ============================================================
   SAWYER HOUSE TOOLS — shared.css
   ============================================================
   Drop-in replacement. Same class names and structure as before,
   retuned to the Writer/Performer direction so the skin no longer
   has to fight it:

     - Nitti Grotesk for the interface, Nitti Typewriter for the
       page and numeric readouts. No Fraunces, no IBM Plex Mono.
     - The cooler ground (#f3f2f2 / #201e1d) and the single red.
     - Nothing in the chrome below 12.5px; 40px control height.
     - Rules carry real weight: hairlines at 0.4 alpha, 2px on
       structural edges.

   Link it once, AFTER the font kit:

     <link rel="stylesheet" href="wp-fonts-nitti.css">
     <link rel="stylesheet" href="/shared.css">

   Trimmed from the previous version: the Google Fonts dependency,
   the brand-crumb hover expansion, --shadow/--shadow-lg (both were
   already none), and the .section-title::after reset (the trick it
   undid is gone).

   THEME: set on <html>. Default is paper (light).
   data-theme="noir" is dark. Both share identical structure.
