/* Chris Fratz — portfolio. Loaded after /shared/css/base.css (Fratz Contact Center Tools tokens:
   Fraunces + IBM Plex Sans/Mono, warm paper / deep teal ink, light + dark). The portfolio's own accent is the
   amber; teal is the supporting ink. No inline styles: every visual state is a class here. Dynamic values
   (bar heights, rail positions, reveal delays) arrive as CSS custom properties set via the CSSOM. */
