FG UI 1.2.0 Release Candidate 1

64 additive families. The 393-family 1.1 contract stays intact.

FG UI 1.2.0 is feature-frozen at 457 component families — 223 Basic and 234 Combined — while preserving all 393 FG UI 1.1.0 public families. Nothing in the ALT collection silently replaces an existing 1.1 component.

FG UI 1.2.0 is Stable.

This website package loads the exact FG UI 1.2.0 Stable runtime. Automated release gates, manual browser/device/NVDA checks, visual review and the 1.1 → 1.2 compatibility sign-off are complete.

Framework capabilities

1.2 is more than new CSS families.

NEW API

Theme system

FGUI.theme adds register, apply, clear, preview, clearPreview, list and get. Theme packages remain token-based and opt-in.

NEW API

Reader preferences

FGUI.reader adds persistent text-size controls with small, normal, medium, large and extra-large reader values.

Theme Package Specification

A common theme manifest, compatibility model, preview/activation path and token package format is now defined so future platform ports can consume the same themes.

1.1 compatibility lock

The frozen 393-family 1.1 contract remains a required subset of FG UI 1.2.0 Stable. Removed 1.1 families: 0. Automated compatibility checks and the final real-browser 1.1 → 1.2 sign-off are complete.

Stable release status

FG UI 1.2.0 completed the release gate.
