/*
  Classic visual layer for ethanmacdonald.ca.

  The site intentionally inherits a browser-like, low-design feel:
  plain white page background, dark text, blue underlined links, a centered
  roughly 900px page, and a 200px left navigation column on desktop. Layout
  classes are explicit so generated fragments do not depend on historical
  table/inline-style inheritance.
