What form of lime does Wikipedia say Pad Thai is served with?

Wikipedia says pad thai is served with lime wedges.

The wedges are usually placed beside the noodles so diners can squeeze fresh juice over the dish immediately before eating. That citrus adds acidity and brightness to pad thai’s sweet, salty, sour, and savory balance, especially alongside tamarind, fish sauce, sugar, and chili.

Lime is not generally cooked into the noodles at the start. Instead, it is commonly offered as a condiment with other accompaniments such as crushed roasted peanuts, bean sprouts, garlic chives, and chili. This lets each diner adjust the flavor and sharpness.

A common mix-up is confusing lime wedges with lemon wedges. They are not interchangeable in the article’s wording, even though restaurants outside Thailand may use different citrus or omit it altogether. Pad thai can also vary by region, vendor, and dietary preference, but the classic serving description identifies lime wedges as the expected garnish.
