Page

• Basic view by default (Advanced via toggle, kept in the URL): setup and results side by side, expected loss a year per setup, the extra cost, the net average, the break-even rate as "years without an incident", the chance-the-solo-setup-is-ahead heatmap, and the lockout caveat. Advanced adds the incident deep-dive, outcomes, timeline, simulation charts, every assumption and the methodology.
• Compares the same operators running separately (solo operators, Stage 0) vs together (multi-operator DV, Stage 1); default 4 operators.
• Area-true squares replace the log bars.
• Help text moves into accessible info tips; preset chips become one-line segmented controls.

Model

• A multi-operator DV is affected as a whole by any operator's incident (replacement costs and residual risk on the full stake); the simulation treats it as one pool.
• DV outage loss is (1 - cover) of the same outage at a solo operator, on the same stake.

Site-wide contrast

• Brand green darkened to #256b57 (light theme).
• Text-safe risk colour tokens for words; fills unchanged.
