HtmxAttributes

Mixin providing the typed HTMX hx-* attribute DSL for zio.blocks.html.

Typical usage is through the package object via import zio.http.htmx._. Attribute keys in this trait delegate value rendering to ToHtmxValue, so custom domain values can participate in the DSL by defining their own instances.

Event-handler attributes are exposed through hxOn, which writes literal JavaScript expressions to hx-on:* attributes instead of generic string values.

Most attributes are intentionally narrower than plain HTML strings. For example, hxSwap accepts HxSwap, hxTarget accepts HxTarget, and selector-only attributes accept CssSelector. This makes accidental stringly misuse fail at compile time while keeping explicit URL/string surfaces for request attributes.
