Two lines in the docs describe switch.predbat_car_charging_from_battery backwards:

• what-does-predbat-do.md: Hold for car said it "requires … car_charging_from_battery to be set to On".
• customisation.md: the switch list said it would "prevent the car from draining the home battery".

The switch defaults to Off (config.py), and Off is what holds the battery while the car charges: execute.py and plan.py only hold when not self.car_charging_from_battery. On lets the car drain the battery, which is how car-charging.md already describes it.

Docs only.

Review of head commit b70573bd — clean, no findings. Both corrected sentences now match the code, and the PR fixes the only two inverted descriptions in docs/.

What I checked:

• Default: car_charging_from_battery defaults to False (apps/predbat/config.py:972), so "Off (the default)" in docs/customisation.md:328 is correct.
• Hold polarity: every hold gate keys on not self.car_charging_from_battery — apps/predbat/plan.py:1283, plan.py:4299, plan.py:4405, plan.py:4721, apps/predbat/prediction.py:928, apps/predbat/execute.py:955 — so "requires ... to be Off" in docs/what-does-predbat-do.md:118 and "when Off, Predbat holds the battery" are correct, and On letting the car drain the battery is correct.
• Completeness: I grepped all of docs/ for car_charging_from_battery; every other mention already describes the correct direction (docs/car-charging.md:45, :48, :222, :1045-1046, :1057; docs/predbat-plan-card.md:100; docs/apps-yaml.md:2206; docs/customisation.md:195), and these two lines were the only inverted ones. The detailed nuances (discharge rate 0 only with a timed pause or outside a charge window, per docs/car-charging.md:1047-1048) live on the Car Charging page this list entry links to, so the one-line summary level is right.

Docs only, no new page, so no mkdocs.yml or CONFIG_ITEMS change is needed; no test coverage obligation applies to a doc fix.
