/* ==========================================================================
   TOWN OF LISBON, MAINE — WEB DESIGN SYSTEM
   v1.0

   Shared tokens, chrome and components for town web applications.
   Import this FIRST, then a page-specific stylesheet for anything unique.

     <link rel="stylesheet" href="lisbon-design.css">
     <link rel="stylesheet" href="my-page.css">

   Rules that keep pages consistent:
     1. Never hardcode a colour, radius or shadow — use a token.
     2. Single light theme. Do not add prefers-color-scheme blocks.
     3. Scope responsive queries to `screen` so printing is unaffected.
     4. Uppercase labels use .eyebrow, never a bare <h2> with custom styles.
