# Parser.LowercaseAlphabet

The lowercase ASCII character union.

## Signatures

```ts
type LowercaseAlphabet = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" | "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" | "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z";
```

## Why

The parser avoids widening literal route names to arbitrary strings.

## Ownership and lifetime

`LowercaseAlphabet` is a string-literal union used only during compiler evaluation and is erased from emitted JavaScript.
