~300 lines of code that were independently duplicated in Dashboard.tsx and Comparison.tsx are now in shared modules: - src/lib/locale.ts — LC interface, EN and AR language configs (merged fields from both pages into one unified interface) - src/lib/dateHelpers.ts — MONTH_KEYS, isLeap, makePresets, guessPreset, periodNameL, dateRangeTextL, currentMonth, shiftYear - src/components/shared/PeriodPicker.tsx — InlinePicker + PeriodHero - src/components/shared/AltMultiSelect.tsx — AltMultiSelect - src/components/shared/MetricCard.tsx — MetricCard Dashboard.tsx and Comparison.tsx now import from these shared modules. Zero behavioral changes — all props, ARIA, and render output unchanged. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
