v0.0.2

Added

• A "How it works" diagram in the README, one render per language, generated from a single layout by scripts/make-readme-diagram.mjs.

Changed

• README head is a machine-readable name / description table, so a reader — human or model — can tell what the plugin is before reading any prose.
• README install order: the repository spec comes first, because the package is not on npm yet.
• README "What it writes to disk" spells out the persistence: the session workspace only, no network calls, no uploads, no telemetry, 200 figures per session, and a figure is a reference rather than a copy.
• README dropped its Releasing and Known issues sections. Release steps now live in docs/MAINTAINER-NOTES.md, together with the open defects.
• Line endings are LF everywhere, matching the .gitattributes the repository declares.

Fixed

• Figures are readable in a dark GUI. A rasterizer has no prefers-color-scheme, so the PNG kept the stylesheet's light values on a transparent canvas and left titles, axis labels and timeline labels dark-on-dark. The PNG now gets an opaque canvas; the archived .svg stays transparent and theme-adaptive.
• Concurrent draws no longer collide. Three or more same-slug draw_figure calls in one step could fail to allocate a file name. A retry now re-reads the directory instead of incrementing a number that was read before the first write.
• The CHANGELOG carried two ## [Unreleased] headings, which made scripts/release.mjs read an empty section and refuse to release.
