    Release: patinate v0.2.0 
    patinate v0.2.0

Pre-1.0: this release breaks configuration (a salt is now required).

## v0.2.0 -- privacy zone no longer outlines home

### Breaking
- Any render with an obfuscation radius above 0 now requires
  `[privacy] salt` (or `PATINATE_PRIVACY__SALT`): at least 16
  characters, kept private, never changed. Generate one with
  `openssl rand -hex 16`. Without it the render stops with an error
  naming the key. Radius 0 and the non-render commands need no salt.
- New `[privacy] offset_m`, default 750, minimum 250 for any positive
  radius. A non-finite or negative radius is now refused.
- Contributors: the Makefile is replaced by a justfile, pinned with
  `just` and git-lfs in `mise.toml`.
- The published crate no longer ships fixtures, `web/`, assets or
  examples.

### Security
- v0.1.x clipped every track at one exact circle around home, so the
  cut ends outlined it. A circle fit recovered home to within metres
  from the SVG, and to about 40 m even from a PNG. The hidden zone is
  now offset from home in a salted, secret direction, and each cut end
  is trimmed a further salted distance along the track. Renders that
  share a salt share one zone centre, so renders at different radii
  cannot be intersected.
- Residual: tracks still converge toward home, and a determined
  analyst can narrow it to roughly 100-250 m.
- Upgrading and re-rendering is strongly recommended. Replace any
  render published with v0.1.x.
- `--web` simplification and coordinate rounding can no longer draw a
  line inside the home radius.
- The zone derivation is pinned by golden tests, so a dependency
  update cannot silently move a salt's zone.
- The cache, which holds the Strava refresh token, and patinate's data
  directory are created owner-only (0600 and 0700), and existing ones
  are tightened.

### Added
- `--fit cover` fills a viewbox of any aspect by cropping the long
  axis. `contain` stays the default.
- `heat.blend` theme field (normal, multiply or screen). The default
  multiplies on a light ground and screens on a dark one, by luminance.
- The heat glow is a `<use>` stack over one path group, not three
  copies of every path. Posters shrink by about a third.
- `--web` writes compact, merged paths sized to the viewbox and drops
  streams, keeping rivers and canals.
- Fixtures are now fully synthetic, with the OSM basemap in git LFS.
  Examples and `render_smoke` run from a fresh clone.

### Fixed
- Equal-sized road components rank deterministically, so two renders
  of the same input keep the same roads.
- `fetch-osm` accepts negative coordinates.
- The Overpass User-Agent reports the crate's real version.

### Changed
- oauth2 no longer pulls in a second HTTP client and TLS stack.
- Dependencies refreshed.

    Release: patinate v0.1.1 
    v0.1.1 -- darwin build fix

Patch release. Same code as v0.1.0 plus one rust-toolchain.toml line
(`targets = ["aarch64-apple-darwin"]`) so the nomograph rust-cli CI
image's prepared darwin target reaches the pinned 1.94.0 toolchain.
The v0.1.0 tag pipeline failed `build:darwin-arm64` for this reason;
v0.1.0 still landed on crates.io but had no GitLab Release artifacts.

This release ships both linux-amd64 and darwin-arm64 binaries plus
SBOMs and cosign signatures via the GitLab package registry.

`cargo install patinate` picks up v0.1.1 automatically. Existing
v0.1.0 installs are functionally identical.

See README.md for install + quickstart, CHANGELOG.md for the full
v0.1 feature surface, CONTRIBUTING.md for the dev loop.

    3f136da4 · docs(changelog): cluster --anonymize / --obfuscation-radius-m with the other render flags · 
    v0.1.0 -- first public release

Render Strava activity into stylized heatmap posters and inline SVG.
Real polyline-circle obfuscation. Privacy flags for shippable renders.

Highlights
- patinate auth/sync/fetch-osm/render flow, end-to-end for one
  rider in one city.
- Real polyline-circle clipping (replaces v0-era naive start-point
  check) with a load-bearing privacy invariant test.
- --anonymize + --obfuscation-radius-m for renders destined for
  public publication.
- Four embedded themes (noir_heat, blueprint_heat, warm_beige,
  cycle_heat) plus --themes-dir for custom JSON themes.
- --web preset (single-layer heat, precision-1 coords, no minor
  roads) for inline page embeds.
- --heat-bloom + --heat-alpha runtime knobs to tune the glow stack
  per render.
- 44 lib tests, cargo audit clean, cargo deny clean, clippy clean
  on rust 1.94.

See README.md for install + quickstart, CHANGELOG.md for the full
feature list, CONTRIBUTING.md for the dev loop, SECURITY.md for
disclosure policy.

Built on storr runner. Cross-compiled to linux-amd64 + darwin-arm64
via the nomograph rust-cli component. Cosign-signed; SBOMs in the
GitLab package registry.
