Site: the devlog, the blog's roro9stack posts in the site's style; Devlog replaces Blog in the navigation

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.

With the antenna switched off, the chip hears only itself: -112 dBm at 250 kHz, about -115 at 125 kHz. At the desk, on USB with Wi-Fi on, the band sits at -101 dBm. Outside on battery with Wi-Fi off, -99.5; with Wi-Fi on, -97. Moving away from the desk didn't help and Wi-Fi accounts for 2 or 3 dB: most of the 15 dB above the chip's own floor comes from the Cardputer itself.">
