/* ==========================================================================
   site.css: page components built on top of tide.css
   --------------------------------------------------------------------------
   tide.css is the design system (kept verbatim from PORTFOLIO_STYLE.md).
   This file only adds the pieces the pages need on top of it, and it only
   uses tide.css tokens, so both themes keep working.

   Sections
     1. Home: about, skills, experience, contact
     2. Footer + back-to-top
     3. Case-study pages (project pages)
     4. Small grid layer for the project pages (replaces Bootstrap's grid)
     5. Prev / next project + image zoom
