Tokens Boutique

We are improving the site day by day, and thus here is small but highly desired feature.

FEATWe added a Vendor dropdown next to the input and output token fields in the calculator. Pick a vendor and the model table below filters down to just their models.

Switch it to a specific vendor, say Anthropic, and the table narrows instantly.

FIXThe calculator and the toggles above it now wrap properly on narrow screens instead of squeezing everything into one row.
