Site / build (pull_request) Successful in 9s
Seven posts imported into site/content/devlog/ with their text unchanged, links between them pointing to /devlog/, and shortcodes (sign, cast, steps, asides, folded sections, diagrams, captions) restyled in the site's palette. The 17 inline SVG diagrams carried <style> blocks and style attributes the site's Content-Security-Policy refuses: their rules moved to devlog-diagrams.css, and a diagram's minimum width is a class. An Atom feed at /devlog/atom.xml. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 760 270" role="img" aria-label="How the satellite list is built. GSV sequences arrive per constellation and per signal band: GPS on L1 lists satellites 5, 13 and 15; GPS on L5 lists 5 and 13 again; GLONASS lists 70. The parser keeps each sequence until its last message, then merges them by constellation and satellite number, keeping the stronger signal: GPS 5 at 42 dB-Hz rather than 30, GPS 13, GPS 15, GLONASS 70. Then the GSA sentences, one per constellation with a system ID in their last field, mark which satellites the Fix uses: system 1, GPS, uses 5 and 13. GPS 5 and BeiDou 5 are different satellites, which is why the system ID matters.">
