GraphCompose v2.0.0 — the modular split

v2.0.0 is live on Maven Central — the first major release. The theme: the monolith becomes modules. The engine that shipped as one jar is now assembled from focused artifacts, so you pull only what you need — while the graph-compose coordinate stays a batteries-included, drop-in dependency.

• Modular engine — the layout + pagination core now builds under graph-compose-core (lean; it throws MissingBackendException if asked to render without a backend). The PDFBox backend moved to graph-compose-render-pdf, and the built-in presets to graph-compose-templates (opt-in). The semantic graph-compose-render-docx / graph-compose-render-pptx, plus graph-compose-testing, graph-compose-fonts, and graph-compose-emoji, round out the set.
• graph-compose stays a drop-in aggregator — one dependency that pulls core + the PDF backend, so an existing graph-compose dependency keeps compiling and rendering PDF unchanged. Bump 1.9 → 2.0 and the common path barely moves.
• Reproducible PDF output (@Beta) — PdfFixedLayoutBackend.builder().deterministic(true) pins the CreationDate / ModDate and derives the PDF /ID from the document metadata, so the same document renders to byte-identical PDF bytes across runs — for reproducible builds and byte-level output tests. Off by default; multi-section documents opt in via the new MultiSectionDocument.toPdfBytes(...) overloads.
• Layered templates are the single surface — templates.cv.*, templates.coverletter.*, templates.invoice.*, and templates.proposal.*, all on one BrandTheme. The classic (pre-layered) presets and the .v2 package suffix are gone (the latter is a package rename only — rendering is unchanged).
• A leaner core — the standalone BusinessTheme token bundle, the DSL name-aliases (builder() / text()), the PDF-typed document-chrome overloads, and the dormant Entity-Component-System engine internals have all been removed. None were on the live render path, so document layout and PDF output are unchanged.

This is a real major — binary-breaking by design (the japicmp gate runs report-only for the 2.0 cycle). The removals above are the breaking surface; the 2.0 modules migration guide walks the moves. For most callers on the drop-in graph-compose path, the upgrade is a version bump.

Drop-in (PDF included):

<dependency>
    <groupId>io.github.demchaav</groupId>
    <artifactId>graph-compose</artifactId>
    <version>2.0.0</version>
</dependency>

Lean (core + pick a backend): depend on graph-compose-core:2.0.0 plus graph-compose-render-pdf:2.0.0. Want the built-in presets too? Add graph-compose-templates:2.0.0.
