/* ==========================================================================
   walkthrough-1.draft.css — shared "walkthrough player" chrome (version 1).

   The structural CSS common to the three shipped players (agentic-form-filling,
   court-bundles-agentic-paths, docx-maintenance-loop): the framed two-pane
   layout, the controls row, the progress dots, the caption line, and the
   cumulative reveal transition. Pairs with walkthrough-1.draft.js.

   Tokenised against plan-1.css (--border, --card-bg, --muted, --ink) where the
   originals used raw hex. The player's own accent (originals: product purple
   #7547F8; docx page: terracotta var(--accent)) is a single overridable token,
   --wt-accent, so per-page LOOK — bubble/preview/panel styling — stays OUT of
   this file and lives in each page's stylesheet.

   Markup contract (role-driven, prefix-free): a `.wt` root containing
   [data-wt="left"], [data-wt="right"], [data-wt="dots"], and the
   [data-wt="prev|play|next"] buttons; optional [data-wt="status"]/["caption"].
   Left-pane items carry `data-step`; the engine toggles `.show`/dot `.on/.done`.
