v0.1.0-rc.1

Release candidate: the first published build of every port, for integration
testing ahead of 0.1.0. npm publishes under the next dist-tag, PyPI as
0.1.0rc1, Maven Central as 0.1.0-rc.1, SwiftPM from the v0.1.0-rc.1 tag.

Initial release of the guided fixation reading algorithm specified in
docs/SPEC.md, with one first-party port per platform runtime and identical
output across all of them.

Ports

• @smooth-reading/core (TypeScript, npm): tokenize, toHtml,
  applyToElement with restore, createTransformStream, fixationLength,
  defaults, defaultSkipTags and styles.css. Word breaking uses
  Intl.Segmenter when available and the spec regex otherwise.
• SmoothReading (Swift Package, iOS 15+/macOS 12+/watchOS 8+/tvOS 15+/
  visionOS 1+): NSAttributedString with real bold fonts plus UILabel,
  UITextView, NSTextField and NSTextView helpers, AttributedString for
  SwiftUI, html() and tokenize(). ICU word breaking via
  enumerateSubstrings(.byWords) and CFStringTokenizer for a locale.
  Resolvable from the repository root via SwiftPM.
• io.smoothreading:smooth-reading (Kotlin, minSdk 24): pure-JVM
  smooth-reading-core plus spanned() for TextView and
  annotatedString() for Compose, ICU BreakIterator word breaking.
• smooth-reading (Python 3.10+, PyPI): tokenize, to_html, to_markdown
  and the smooth-reading CLI; regex-equivalent tokenizer with no
  dependencies.

Algorithm and options

• Fixation strength 1–5 with the ratio table 0.20 / 0.35 / 0.50 / 0.65 / 0.80,
  round-half-up, clamped to 1…n grapheme clusters; saccade,
  minWordLength, emphasizeNumbers, locale and a fixationLength
  override.
• Out-of-range fixation and saccade are clamped into range in every port.
• HTML rendering passes existing tags and character references through,
  never emphasises text inside code, pre, script, style, kbd,
  samp or textarea, never nests emphasis, and emits neutral markup styled
  by CSS custom properties.

Fixtures

• Shared JSON fixtures under fixtures/common/ (basic, edge cases, markup,
  options, saccade, scripts) that every port must pass, and
  fixtures/segmenter/ (CJK, extended CJK, bidi) for ports with an ICU word
  breaker. Every port also checks that token texts concatenate back to the
  input and that the markup with emphasis tags stripped equals the escaped
  input.

Languages

• Chinese, Japanese, Korean, Thai, Vietnamese, Hindi and other Indic
  scripts, Arabic, Hebrew, Persian and Urdu are first-class: dictionary-based
  word breaks where ICU provides them, grapheme-cluster counting so combining
  marks, Indic conjuncts, Thai vowel signs, Hangul jamo and emoji sequences
  are never split, and bidi ordering is never altered. Details and known
  engine differences are in docs/LANGUAGES.md.

Documentation

• docs/SPEC.md (the contract), docs/LANGUAGES.md, copy-paste framework
  recipes in docs/recipes/ (React, Vue, Svelte, Angular, React Native,
  web component, Markdown pipelines) and a Vite playground in
  examples/playground/.
