/* ════════════════════════════════════════════════════════════════════
   WALLER SUPPLY — SHARED DESIGN SYSTEM  (single source of truth)
   --------------------------------------------------------------------
   Every page links this file. DO NOT copy these rules back into a page's
   inline <style>. To change the nav, hero, buttons, footer, colors, or
   type scale site-wide, edit THIS file once.

   HERO TIERS (set on the <section>/<header class="hero">):
     • class="hero"                → tall hero  (home + main service pages)
     • class="hero hero--compact"  → shorter hero (listing/utility pages
                                      e.g. industries, resources)

   To start a NEW page: copy _template.html — it already links this file
   and uses the canonical nav / hero / footer markup, so it inherits all
   of these rules automatically.
