Replaces the generated SVG charts in the README with charts of the documented household itself, rendered by evcc from a local instance with demo devices: a 10 kWh home battery at 50 %, a 50 kWh EV at 20 % that must reach 80 % by 08:00, a 4 kWp PV forecast and a dynamic tariff between 18 and 44 ct. Light and dark variants via <picture>. Three images: the charging plan with charge_before_export, the SoC projections, and the charging plan with attenuate_grid_peaks on the same household, so the peak levelling section shows the refill spread over the solar window and the feed-in plateau.

Every chart comes from a solve reported Optimal, locally under the production 10 s limit and replayed on the hosted optimizer (1.1 to 7.7 s). The EV charges on one phase, 3.7 kW: with the three phase 4.1 kW minimum the same request never proves, which is filed separately with the requests attached.

Separate from #180, which only touches the solve table.

Screenshots of a real household from evcc's experimental optimizer page,
light and dark, replace the generated charts. The example and the peak
levelling sections describe what they show.

A local evcc with demo devices reproduces the documented spec: 10 kWh
battery, 50 kWh EV that must reach 80 % by 08:00, 4 kWp forecast,
18 to 44 ct tariff. All three solves are Optimal, locally and on the
hosted optimizer. The EV charges on one phase: the three phase shape
with a 4.1 kW minimum never proves, see the issue on those requests.
