Highlights — the browser is gone (#409)

v4.0.0 completes the chromedp/Chromium elimination. The rendering pipeline is now fully self-contained:

  • Docker image: ~830 MB → 227 MB — no chromium package at all; PNG/JPEG rasterize through a bundled ~6 MB resvg binary
  • Native SVG output — every card renders as pure SVG (no <foreignObject>/HTML); heights are computed in Go with bundled Liberation Sans font metrics, so SVG output needs no renderer at all
  • Faster renders — the 2.4 s per-render measurement sleep and browser startup are gone
  • The "distro chromium update silently breaks rendering" failure class is structurally eliminated (the incident behind #666 / 7ca0d59 cannot recur)

⚠️ Breaking / behavior changes

  • Generated SVG structure changed completely. Anything depending on the old markup (foreignObject/HTML, CSS classes, exact bytes) will see a one-time diff. Data attributes (data-section, data-plugin, …) are preserved.
  • PNG/JPEG are rasterized by resvg with Liberation Sans instead of a headless Chrome screenshot — expect small font-rendering differences.
  • Default padding is now 0 (was "0, 8 + 11%"); cards are more compact. The config_padding input still works and is applied arithmetically.
  • METRICS_CHROME_PATH is gone; METRICS_RESVG_PATH points at the rasterizer (preset in the image). Local dev no longer needs any browser.
  • Input interface (plugin_*, chrome_*, CLI flags) is unchanged from v3.1.0.
