Every fix in this release was discovered by pixel-verifying captures of real sites and adversarial fixtures in headless Firefox, and each landed with before/after screenshot evidence and pixel-level regression tests (the suite now covers 11 fixtures).

• Sticky elements inside shadow DOM no longer repeat on every stitched frame — detection now descends into open shadow roots, both in viewport sampling and the full-scan fallback (#10).
• Infinite-scroll pages are no longer truncated at their pre-capture height — dimensions are re-measured after the lazy-load pre-pass, with bounded grow passes so endless feeds still terminate (#11).
• Transform-based smooth-scroll sites (Locomotive/Lenis style) no longer produce ~90% blank output — a full-viewport fixed wrapper on a scrolling document now routes to the scroll-and-stitch path, and such content wrappers are exempt from overlay hiding (#12).
• Fixed bottom overlays (cookie consent banners, chat bubbles) no longer blot out a stripe of content — bottom-anchored overlays are hidden before the first frame in all capture modes, with dense bottom-edge detection that catches narrow off-center widgets and overlays recreated by SPA re-renders mid-capture (#13).
• Lazy-loaded images below the fold no longer capture as blank placeholders — the capture waits (time-bounded) for triggered images to finish decoding (#15).

• Sticky sidebars and TOCs no longer repeat in every stitched frame. Fixed elements are hidden and sticky elements un-stuck after the first frame, re-applied on every tile so SPAs that re-render while scrolling (e.g. the Cloudflare dashboard) stay clean.
• HiDPI / page zoom output no longer scrambled — full-page stitching now scales by devicePixelRatio.
• Pages with scroll-behavior: smooth or scroll snapping no longer capture mid-animation.
• Right-edge sticky elements (missed when a scrollbar was present) are now detected.
• Inner scroll containers with borders no longer shift the capture by the border width.

• Direct render path: on normally-scrolling pages the entire page is rasterized in a single tabs.captureTab call — no scrolling, no seams, much faster — with a lazy-load pre-pass and automatic fallback to scroll-and-stitch.
• Chrome preservation for app dashboards: when the content scrolls in an inner container, the sidebar/header/footer around it now appear once in the output instead of being cropped away.
• Real-Firefox E2E suite (test/e2e/) with pixel-verified capture output, plus debug-page.js for capturing any URL headlessly while debugging.

• Replaced fixed per-tile 400ms delay with paint-aware
  wait.
• Reduced jank on large pages by avoiding full DOM scans
  where possible.

FullPage Capture v0.3.0 — Release Notes

• New Capture Modes

Visible Area (Alt+Shift+2)
Capture exactly what's on screen — no scrolling, instant.

Select Region (Alt+Shift+3)
Draw a rectangle, capture that area. Esc to cancel.

Scrolling Selection (Alt+Shift+4)
Capture regions that extend beyond the viewport:
1. Draw a rectangle
2. Scroll freely — selection stays anchored
3. Drag handles to adjust (auto-scrolls near edges)
4. Click Capture
