v1.4.0 — UI Motion Storyboard

Highlights

• Adds a first-class UI Motion storyboard workflow for four-frame interface-state storytelling.
• Preserves exact in-frame Chinese copy and separates viewer-facing UI from production metadata.
• Restricts #FF6A2A to active semantic states, keeps inactive frames charcoal/gray, and distinguishes pointer interaction from hand/finger interaction.
• Excludes visible frame IDs, shot numbers, duration labels, review arrows, and production annotations after a single-variable visual retry exposed unwanted 01–04 labels.
• Adds a validated UI Motion example, dedicated workflow reference, CI coverage, README/README.zh-CN documentation, and 162 regression tests.
• Corrects evidence wording for the existing intro infographic example so local/manual review is not overstated as receipt-bound public execution evidence.

Verification

• Local release gate: 162/162 tests passed; Ruff 0.16.3, schema validation, prompt lint, reference preflight, compilation, and diff checks passed.
• Independent cold review: PASS with no high-confidence findings.
• GitHub Actions: feature branch, main, and tag workflows passed.
• A session-only visual forward test passed after the metadata-exclusion retry; it is not committed or claimed as public execution evidence.
