   KEN ZILLIG PERSONAL RESEARCH WEBSITE — STYLESHEET
   ================================================================
   
   HOW TO MAKE COMMON EDITS:
   
   - Change site colors: edit the values under ":root { }" below
   - Change fonts: edit the font-family values under ":root { }"
   - Adjust spacing: look for "padding" and "margin" values
   - Make text bigger/smaller: look for "font-size" values
   
   COLOR GUIDE (current palette):
   --ink:       very dark navy — main text color
   --deep:      darkest background (hero, footer)
   --water:     deep blue-green — primary accent
   --water-mid: medium teal — secondary accent  
   --sand:      warm off-white — light background sections
   --paper:     near-white — default page background
