/* The Sprayers — themes.
   ------------------------------------------------------------------------
   Loaded after app.css. Each theme overrides the custom properties app.css
   already uses, plus a handful of chrome rules where a different look needs
   more than a colour change.

   Nothing here touches the print stylesheets. A quotation or invoice must look
   the same whoever printed it and whenever — the theme is for the people using
   the system, not for the documents leaving it. */


/* ============================================================ MODERN =======
   Lighter chrome, more breathing room, one accent colour used sparingly.
   Same information density — a workshop screen still has to show forty rows
   without scrolling forever. */
