/* styles.css: Kaizen Weaver.
 *
 * Brand tokens (colors, type scale, font faces) live at the top, then app
 * styles for the three views and the shared chrome below. Built from the
 * design_handoff_weaver prototype, consolidated into a single stylesheet
 * because the production app loads only one CSS file.
 *
 * Voice: paper-and-ink editorial. Serif body (Cormorant Garamond),
 * sans UI (Inter), handwritten accent (Caveat). Nothing pill-shaped except
 * the gold CTA. Surfaces are warm off-white; ink is near-black.
