Base assets and curves

A launch is priced in exactly one base asset, chosen at creation from what the registry whitelists. Read the live list from ConfigRegistry.getEnabledBases() rather than hardcoding it: the owner can add or drop an entry at any time, and a launch against a base that is not enabled reverts with BaseNotAllowed.

Each base carries its own curve on the registry, read as baseCurve(base) returning (startAmount, fillAmount). startAmount is the valuation a launch opens at and fillAmount is what the main band must take in to graduate, both denominated in that base.

baseFillAmountActual(base) is the figure the hook actually settles against, and it is slightly above fillAmount because the band is priced in ticks and the target lands inside one. Use it when you need the exact raise, and fillAmount when you need the number the protocol advertises.
