Changes in version 0.2.0 (2026-06-24)                  

  - Added a standalone static HTML/WebGL export via export_static_app().
  - Added an embeddable standalone applet article and pkgdown home-page
    iframe.
  - Added configurable preview horizons, horizon-specific high scores,
    autoplay helpers, strategy benchmarks, and growth-focused lookahead
    support.
  - Fixed cascade resolution so active-tile merges are followed by
    deterministic board-wide by-product merge scans until the board is
    stable. This keeps the Rcpp and standalone browser engines aligned
    when gravity creates adjacent equal-value tiles away from the active
    tile.
