Solving Responsive Breakpoints from Content: study data, scripts and corpus

Everything behind the numbers, tables and figures of the paper "Solving Responsive Breakpoints from Content: Exact Critical Widths for Declarative Web Pages" (Vabroušek, Jašek, Vala; submitted to MDPI Algorithms): the corpus of Nodality (E, N) pages with a SHA-256 checksum per page, the seeded generator of the synthetic pages, the sweep and property scripts, the packed Nodality 1.4.0 release candidate they ran against (with its SHA-256), the raw result of every page and arm at every measured width, and reproduce.py, which derives every number, table and figure in the paper from those results. Reproduce the paper's numbers offline: cd study && python3 reproduce.py --check (Python 3 standard library only). Re-running the measurements needs Node.js, Playwright 1.59.1 and Chromium; see study/README.md. Licences: scripts MIT (LICENSE); corpus, results and documentation CC BY 4.0 (LICENSE-DATA).
