/*
  J. Shea Technologies - site styles ("Silver Ring" look)
  Plain CSS, no build step. Mobile first.
  Colors come from the logo: navy #1B2A41, olive #5B6B4A, sage #919C86,
  silver #A8A8A8. Dark mode is a navy version of the same look.
  Fonts: IBM Plex Sans (text), IBM Plex Mono (labels and buttons),
  Libre Caslon Text (the "J. Shea" wordmark). All three load from
  Google Fonts; system fonts take over if they don't load.
  Sections:
    1. Tokens (light + dark)
    2. Base
    3. Layout utilities
    4. Buttons, labels, placeholders
    5. Header, brand and menu
