Typed styles

Types at author time. CSS at run time.

Stable 128-bit identities connect Rust source, emitted classes, manifests, and physical declarations.

One literal, one stable identity

pc! accepts one visible string literal. The macro parses semantics, rejects conflicting slots, and returns a sealed Style.

const CARD: Style = pc!(
  "grid gap-4 rounded-xl border border-line p-6 shadow-md"
);

pcx! compiles every visible branch combination and selects one identity at runtime. Independent clauses that can collide are rejected.

let style = pcx!(
  "block",
  if active { "opacity-100" } else { "opacity-50" }
);

Manifest schema 5 joins semantic declarations to final rules, conditions, byte ranges, and synthesized effects such as box-shadow.
