Follow-up to #118.

  • EV series is now blue. Two batteries both wearing a green out of evcc's batteryPalette were hard to tell apart in the battery power and state-of-charge panels. The EV takes the palette blue (#2563EB light / #60A5FA dark); the home battery keeps batteryPalette[0].
  • New peak levelling example. The README documented the attenuate_* strategies in one bullet but never showed them. Added a section with a before/after figure: the same house on a flat tariff, once with no strategy and once with attenuate_grid_peaks. Both panels share one scale, so the 11.5 kW import peak collapsing into a flat 3.6 kW plateau — same 29 kWh, same cost — is directly comparable. The feed-in peak drops from 1.3 kW to 0.25 kW in the same run.

Both figures are rendered from real solves, not sketched.

Two batteries in one chart both wearing a green from the evcc battery
palette was hard to read, so the EV takes the palette blue instead. The
home battery keeps batteryPalette[0].

Adds a second example for the peak attenuation strategies, which the
README did not show at all: the same house on a flat tariff, once
without a strategy and once with attenuate_grid_peaks. Both panels share
one scale, so the 11.5 kW import peak collapsing to a flat 3.6 kW
plateau is directly comparable. Figures are rendered from real solves.
