Overview

Ruby evaluates ‘3.px` as Integer#px — a method call on the literal 3. Without this patch, that raises NoMethodError because Integer has no `px`.

Inside a ScopedStringBuilder block, expressions like ‘a.b / 3.px` need the right-hand operand `3.px` to produce an InnerStringBuilder so the `/` operator can cleanly append the separator symbol followed by the operand’s tokens. The problem is that Ruby resolves ‘3.px` before `/` is called, and it resolves it on Integer, not on the ScopedStringBuilder.

The monkey patch bridges this gap: any unknown method on an Integer creates a new InnerStringBuilder, records the integer as the first token via ‘call`, then forwards the method (e.g. `px`) so it chains naturally. The result is a standalone builder that the operator receives as a distinct `other` object — no different from how any other right-hand operand works.
