/* =====================================================================
   P4P Tools — shared on-screen look (app chrome only)
   ---------------------------------------------------------------------
   One copy of the styles every tool's interface uses: colors, fonts,
   top bar, left sidebar, buttons, toast message and footer.

   The standard is the Vax Schedule Builder look (Oct 2026). Values are
   copied from it unchanged — this file does not redesign anything.

   RULES
   - This file styles the APP, never the printed/exported document.
     Print layouts (Vax pages, MDA/Romer/Swine Test Chart forms,
     Treatment Timeline letterhead) stay inside each tool's own file.
   - Every chrome piece below is hidden when printing.
   - A tool may still override anything here in its own <style>,
     as long as it loads this file FIRST.

   HOW A TOOL USES IT (in <head>, from a tool folder):
     <link rel="stylesheet" href="../shared/p4p-ui.css">
