   Pipe-Works — Unified Foundation

   MERGED FROM:
   - shared-base.css (The Daily Undertaking foundation)
   - pipe-works-base.css (Pipe-Works theming)

   PURPOSE
   - Global tokens (fonts, colors, spacing)
   - Minimal reset + accessibility
   - Pipe-works palette and theming
   - Common components (sheet, sticker, ascii, imprint)

   RULE OF THUMB
   This file defines the pamphleteer voice and vocabulary.
   Page CSS (index.css, crooked-pipe.css, etc.) writes sentences.
