### Patch Changes

- [#1259](https://github.com/Ripple-TS/ripple/pull/1259)
  [`3b6fb73`](https://github.com/Ripple-TS/ripple/commit/3b6fb73170d4ad6a383befdda951ce0da4fcbb46)
  Thanks [@leonidaz](https://github.com/leonidaz)! - Lower a code-only `@{ … }`
  block in value position to a `tsrx_element`. The value-position IIFE wrap was
  gated on the block having render output, so a render-less block assigned to a
  variable or returned (e.g. `const Test = @{ const y = 1; };`) was lowered to a
  bare `BlockStatement` and printed as a malformed object literal
  (`const Test = { const y = 1; };`) in client, server, and `to_ts` output. The
  wrap now applies regardless of render output, so a code-only block gets the same
  lowering as a render-bearing one — a `tsrx_element` whose setup runs on render
  and which renders nothing (an immediately-invoked arrow in the `to_ts` view).

- [#1262](https://github.com/Ripple-TS/ripple/pull/1262)
  [`1c645c8`](https://github.com/Ripple-TS/ripple/commit/1c645c8f854df23bb1271b3402d1885616b525cd)
  Thanks [@leonidaz](https://github.com/leonidaz)! - Prune unreachable selectors
  from `<style>` blocks consistently across targets.

  For a style expression (`const styles = <style> … </style>`), only standalone
  class selectors — scoped (`.x`) or global-wrapped (`:global(.x)`) — end up in
  the generated class map, but the emitted CSS still contained every selector.
  Top-level selectors that don't contribute a class map entry (element selectors,
  compound selectors, descendant chains, global tag selectors) are now commented
  out as unused, while standalone classes, `:global(.x)` selectors, and rules
  nested inside a reachable rule (e.g. `&:hover`) are kept.

  Free-standing `<style>` blocks in the shared JSX targets (react, preact, solid,
  vue) now prune selectors that match no element, the same way the Ripple target
  always has, instead of keeping every authored selector. Selector matching also
  recognizes `className` as the class attribute for React-style targets.

- [#1260](https://github.com/Ripple-TS/ripple/pull/1260)
  [`b1256fd`](https://github.com/Ripple-TS/ripple/commit/b1256fdb5bf279ee7dd20bf1a71dcfccc47e279c)
  Thanks [@leonidaz](https://github.com/leonidaz)! - Make style scope hashes
  unique per style block and per file. The hash was derived from the style block's
  content alone, so two `<style>` blocks with identical CSS — in different
  components of the same file, or in different files — collided and shared a
  scope. The hash input now includes the filename and the line/column where the
  `<style>` tag starts. Because the filename may be an absolute path, the hash
  also switched from the reversible djb2 hash to the truncated SHA-256 hash so
  file structure can't be recovered from class names in the shipped bundle.

  The `filename` parameter of `parse`, `parseModule`, and the per-target `parse`
  wrappers is now required (typed as a non-empty string), and parsing a `<style>`
  element without one throws a clear error instead of silently seeding the hash
  with an empty name. The prettier plugin and eslint parser pass their host's file
  path through, falling back to a plugin-specific placeholder when formatting or
  linting in-memory text.
