/*
  Bible Journal — marketing site styles.

  The palette and type are lifted verbatim from the app's design tokens
  (lib/core/theme/app_tokens.dart + app_typography.dart). The app authors color
  in OKLCH and CSS speaks the same oklch(L C H) dialect, so these values render
  identically here and in the app — the site is the app's "Paper" theme in a
  browser, with "Candlelit" as the dark face via prefers-color-scheme.

  Design rules carried over from PRD §9: typography-led, image-light, generous
  whitespace, gentle (never bouncy) motion, restrained color. Everything is fluid
  (clamp/%, no fixed breakpoints required) so it holds from a small phone to a
  wide desktop — screen-size-agnostic, per the project's prime directive.
