/* BookSesh UI — shared design tokens + minimal component classes.
   Tokens/components/assets ONLY — no framework, no layout system, no JS.
   Source of truth for values: mu-plugins/booksesh-home-preview/assets/aura-home.css
   (Plus Jakarta Sans; ink/coral/lavender/paper/stone/blue brand system).
   Consumers enqueue this file directly; nothing here is auto-applied globally —
   every rule is a token or an opt-in `.bks-*` utility class, so importing this
   file has zero effect until a consumer's own scoped CSS/markup uses the vars
   or classes. Currently consumed by: booksesh-session-preview (page-scoped). */
