Deep Hearth is a small, bounded, playable reference ecology in which state, resources, cells, encounters, memory, agency, witness, and Rest can be tested by people at a table.
Markdown in source/ is authoritative.
The publication pipeline generates LaTeX under build/ and produces PDF, EPUB,
and a combined Markdown artifact under output/.
The design target and section plan are in
GOLDEN_SEED_PLAN.md. The repository is licensed under
the MIT License.
The public alpha introduction is in ANNOUNCEMENT.md.
Please use the GitHub issue tracker
for playtest reports, rules questions, and discovered extensions.
The optional generic card substrate is called The Tableau. Magic, ordinary playing cards, tiles, and original cards can all serve as Tableau hosts.

The PDF uses XeLaTeX, matching the Cartomancy book pipeline. Markdown remains the source of truth; generated LaTeX is disposable build output.
Deep Hearth is the open Basin reference body. Its public rules language must remain separate from any private setting substrate, including Forgotten Realms. License, Open Game Content, Product Identity, trademark, and attribution review belongs in the publication pass before any public release.
