Lines drawn in the background (decor) editor showed notched 'teeth' where
two segments met at an angle. Decor <line> elements — both the saved render
and the live drawing preview — now carry stroke-linecap/linejoin=round, so
every line end reads as a circle of the stroke width and joints are smooth.
smoke_decor asserts the round attributes on the draft and the saved lines.
A fully fictional house (plans, devices, states) used for README screenshots,
the demo GIF and headless smoke tests — so no real home data ever appears in
public materials.
srv/demo.html — self-contained host page: <ha-icon>/<ha-card> stubs and a
fake hass (registries, states, callWS, callService, floors).
srv/assets/ — generated plan SVGs and icons.js (node demo/gen_icons.mjs,
needs the repo's devDependencies). The card bundle is copied from dist/:
cp dist/houseplan-card.js demo/srv/assets/.
serve.mjs — playwright launcher (route interception, no web server).
smoke_*.mjs — feature smoke tests; run with a Chromium installed via
PLAYWRIGHT_BROWSERS_PATH=<dir> npx playwright install chromium-headless-shell.
Note for sandboxed sessions: /tmp does not survive; this directory is the
persistent home of the harness (docs/DEVELOPMENT.md has the LD_LIBRARY_PATH recipe).
