Summary

v1.1.0 introduces year-aware theme colors and further modularization of the codebase. Themes can now be determined by a curated COLOR_OF_YEAR mapping, with a small hue-prediction algorithm used for future years. This release also consolidates engine initialization into a lightweight bootstrap and polishes tooltip behavior and watermark appearance.

Notable Changes

  • Year-aware themes
    • js/theme.js exports COLOR_OF_YEAR and THEME_COLORS.
    • TraceEngine.getColorForYear(year) returns a validated color for a given year (exact match, nearest, or predicted for future years).
    • TraceEngine.setThemeByYear(year, { persist = false }) applies the theme and can persist the selected year to localStorage.
  • Modularization
    • js/trace-engine.js contains the core engine (rendering, interactions, theming).
    • js/app.js provides a small bootstrap that instantiates the engine and exposes window.traceEngine for debugging.
  • UX polish
    • Unified tooltip positioning with an above-biased auto-flip.
    • Watermark alpha and radii tuned for improved legibility.
  • Randomization
    • randomizeTheme() and related flows now prefer year-based selection within the engine's supported year range.

Files Changed (high level)

  • Added: js/theme.js (theme constants and color-of-year map)
  • Modified: js/trace-engine.js (theming APIs, tooltip logic, randomization behaviors)
  • Modified: js/app.js (bootstrap wiring)
  • Modified: CHANGELOG.md
  • Added: RELEASE_NOTES/1.1.0.md

Migration / Usage

  • Developers can now programmatically set year-based themes:
    • traceEngine.setThemeByYear(1999, { persist: true })
    • TraceEngine.getColorForYear(2025) returns a hex color string.
  • Default behavior remains unchanged: if you haven't opted to use year-based theme persistence, the saved theme index still controls the initial theme.

Testing Notes

  • Verify theme application across a few representative years (historical, nearest, and future-predicted).
  • Validate tooltip placement across mouse, touch, and keyboard focus.
  • Run accessibility checks for color contrast and ensure announcer behavior remains non-intrusive on load.
