+# Copilot instructions (grimoire-css)
+
+## Project shape (architecture guide)
+
+Note: This document captures the current architecture conventions for this repo.
+- Rust workspace is a single crate with **bin + lib**: `src/main.rs` calls `grimoire_css_lib::start_as_cli` (keep `main.rs` thin).
+- Command routing lives in `src/commands/handler.rs` (`init` / `build` / `shorten`). Add new CLI modes by wiring them here.
+- Core pipeline logic lives in `src/core/` (config → parse → build → optimize → output). Keep it side-effect-light where practical.
+- External integrations live in `src/infrastructure/` (e.g. LightningCSS optimizer + miette diagnostics). Don’t mix vendor glue into `src/core/`.
+
+## Runtime modes & config conventions
+- FS mode uses a single repo config file at `grimoire/config/grimoire.config.json` (created by `init`; used by `build`). See `src/core/filesystem.rs` and `src/commands/init.rs`.
+- Optimizer uses `.browserslistrc` from repo root; if missing, it is created with `defaults` (see `src/infrastructure/lightning_css_optimizer.rs`).
+- Parallel project builds are opt-in via `GRIMOIRE_CSS_JOBS` (project-level isolation) — see `src/core/css_builder/css_builder_fs.rs`.
+- Locking: setting `lock: true` in config enables tracking + cleanup of stale generated files via `grimoire/grimoire.lock.json` (see `src/core/file_tracker.rs`).
+- Config supports external scroll/variable files: `grimoire.*.scrolls.json` and `grimoire.*.variables.json` are loaded and merged during `ConfigFs::load` (see `src/core/config/config_fs.rs`).
+
+## Error/reporting pattern
+- Prefer returning `GrimoireCssError` from core logic; attach source context when you have file content/spans using `GrimoireCssError::with_source(...)` and `SourceFile` (pattern in `src/core/parser/parser_fs.rs`).
+- CLI pretty-printing goes through `GrimoireCssDiagnostic` + `miette` (see `src/infrastructure/diagnostics.rs` and `src/lib.rs`).
+
+## Developer workflows (match CI)
+- Format: `cargo fmt -- --check`
+- Lint: `cargo clippy -- -D warnings`
+- Tests: `cargo test`
+- Coverage (CI uses this): `./scripts/coverage.sh` (requires `grcov` + `llvm-tools-preview`).
+
+## Local running tips
+- CLI (debug): `cargo run -- build` / `cargo run -- init` / `cargo run -- shorten`
+- Release binary: `cargo build --release` → `target/release/grimoire_css`
+- Benchmark harness expects the release binary at `../target/release/grimoire_css` (see `benchmark/README.md`).
+
+## Versioning convention
+- PR branches `rc/x.y.z` must match `version = "x.y.z"` in `Cargo.toml` (enforced by `.github/workflows/version_check.yml`).

 # Changelog
 
+## [v1.7.0] - 2025-12-27
+
+> Full release notes: [releases/v1.7.0.md](./releases/v1.7.0.md)
+
+### Added
+
+- **Scroll templates in `g!…;`**: Use config-defined `scrolls` inside templated syntax with variable arguments.
+- **Rustc-like diagnostics**: File/snippet output with labeled spans and optional help text.
+- **Opt-in parallel builds**: Enable multi-core filesystem builds via `GRIMOIRE_CSS_JOBS`.
+- **Repro sandbox**: Added `repro/` scenarios for quickly validating features and diagnostics.
+- **Contributor instructions**: Added `.github/copilot-instructions.md` describing the repo’s architecture conventions.
+
+### Improved
+
+- Deterministic scroll expansion under templated selectors, including correct propagation of prefixes (`md__`, `{...}`, `hover:`).
+- Reduced redundant work and lowered clone/allocation pressure in hot paths (output unchanged).
+
+### Fixed
+
+- Malformed function-like spell values now produce clearer, earlier errors.
+- Color function argument validation now returns a proper error instead of being silently ignored.
+
+---
+
+## [v1.6.0] - 2025-07-21
+
+> Full release notes: [releases/v1.6.0.md](./releases/v1.6.0.md)
+
+### Added
+
+- Extracted the color module into `grimoire_css_color_toolkit` for independent usage.
+- Comprehensive support for curly-bracket class syntax (`class={}`, `className={}`) with nested bracket handling.
+
+### Improved
+
+- Migrated unit handling from `u32` to `f64` for better precision in responsive calculations.
+- Upgraded to Rust Edition 2024 and set MSRV to Rust 1.88.
