# Assemble the deployed single-file pages from source + shared partials + assets/.
#
# Each page is a source that shares code via markers:
#   /*@BUILD:include:src/<file>@*/   inlines a shared partial (engine, seed lists, base CSS, header/footer/chrome)
#   @BUILD:favicon@ / @BUILD:logo-*@ / @BUILD:bravura@   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.
#
# NOTE: this is the slim `main` branch — only the landing chooser, the mobile app
# (+ its practice journal) and the pm_e-2 notation editor ship. The full
# multi-form-factor project (all device pages, firmware, Rust, hardware) lives on
# the `concepts` branch.
