Self-contained Analytics UI: Overview/Daily/Weekly/Monthly/12-Month/Exercises
with color+glyph status, empty/partial states, Swift Charts, VoiceOver labels,
Wenza tokens, and the non-medical disclaimer. Entry via an IButton in the
Workout header (sheet). Added Identifiable chart points.
Self-reviewed for compile issues (fixed tuple key-paths, a11y trait literal,
format string) but NOT build-verified — no iOS runtime; SwiftUI/app deps. Logged
in ISSUES.md as device-required.
