/* ===========================================================================
   SRR Gutter Estimator
   Design matched to specialistroofing.com and the Specialist Roofing logo.

   Palette and type sampled from the live site:
     blue   rgb(0,63,190)    #003FBE   (logo mark, headings, hero)
     orange rgb(255,107,39)  #FF6B27   (logo underbar, every call to action)
     navy   rgb(7,29,71)     #071D47   (footer, dark bands)
     hover  rgb(32,76,229)   #204CE5

   The live site sets headings in Nexa Slab 900 uppercase and UI text in Nexa.
   Both are licensed Fontfabric faces that cannot be served from a free CDN, so
   this uses Roboto Slab 900 and Montserrat as the closest free equivalents.
   If SRR holds a Nexa webfont licence, swap the two --font-* tokens and the
   <link> in index.html and nothing else changes.

   Mobile first. Most roofing leads arrive on a phone.
