# Assemble the deployed single-file pages from source + shared partials + assets/.
#
# Every page (the landing index.html, the editor.html app, the device mockups and
# the info-*.html pages) is a source that shares code via markers:
#   /*@BUILD:include:src/<file>@*/   inlines a shared partial (engine, seed lists, base CSS)
#   @BUILD:favicon@ / @BUILD:logo-*@ / /*@BUILD:samples@*/{}   inline base64 assets
# This resolves them so each built page in dist/ is one self-contained file
# (zero deps, works fully offline). deploy.sh runs this first. dist/ is generated —
# don't edit or commit it.
