5. run-chart-example — inline-SVG mini charts

How the run-detail chart reads two scenarios — dummy data

Solar / contracted supplyFirm or BESS supplyDemand lineSpill

Midday solar with network losses

Read it: the solar band meets the demand line at noon; the chart stacks delivered kWh.

Firm cover with a top-up gap

Read it: the red ticks are the 2,000 kWh gap priced at grid top-up.

Meter ladder — readings → intervals

Read it: the step is cumulative readings; the amber bars are the interval deltas between them.

6. tab-sample — annotated screen replica

Allocations sample view — dummy data

Hour 1	Kind 2	Sent 3	Delivered 4	Margin 5
12 SAST	ALLOCATION	16,710 kWh	16,142 kWh	R 6,088

1Hour is the SAST settlement interval.
2Kind identifies the line type.
3Sent is injected energy; buy cost is charged on it.
4Delivered is energy after DLF losses.
5Margin is the line’s realised Rand contribution.
