Reorganize the single-scroll page into three purpose tabs (Rekenmodel,
Live dag-strategie, Historie) with the Parameters panel as a persistent
sidebar. Tab state is persisted in localStorage and charts are resized on
activation to avoid 0px canvases in hidden panels; print CSS keeps the full
report.
Also replace the legacy fixed EUR 0,15 spread in the scenario comparator and
payback chart with the dynamic market spread (peakPrice - refPrice), matching
the rest of the tool, and make the related labels reflect it live.
Add .claude/launch.json for local static-preview.
