Each category is a native <details>, closed at first, with an 'n selected' count;
a preset opens what it ticks. A sticky memory bar (0-64 GB, marks 8/16/24/32/48/64+):
solid fill = smallest box memory where the selection fits well, thin mark = where it
fits, but tight; one line names the box to buy. minBoxGb() inverts guestMib() by
bisection on it, so the rule is still written once. Box sizes 12/24/48/64 added;
tests cover seven sizes and the inverse (red-proofed); SIZING.md table gains 24 GB.
A household ticks apps and sees, for an 8, 16 and 32 GB box: fits well / fits, but
tight / does not fit, the totals, and the apps that burst on CPU. One rule in
assets/sizing.js, every number from assets/sizing-data.json (built by
scripts/build_sizing_web.py from the 2026-10-13 N100 measurement; test: 7 cases,
red-proofed). Unlisted: noindex, robots Disallow, not in the sitemap, linked from
nowhere — site_gates.py gate 25 enforces it (UNLISTED twin pairs keep every twin
check). SIZING.md §5 corrected: the 8 GB line contradicted its own x1.5 rule; guest
sizes 4.0/11.4/27.4 GB with the measured 612 MiB MemTotal shortfall. R-993 gains the
fact that the installer accepts a host below any minimum.
