Implementation Plan - Add Calcium to Tracker Totals

This plan follows the Test-Driven Development (TDD) process as outlined in conductor/workflow.md.

Phase 1: Infrastructure and Red Phase

• Task: Create a failing E2E test for Calcium display
  • Define a new test in tests/calcium_display.spec.js that navigates to the tracker and expects a "Calcium" label and a numeric value in the Daily Totals section.
  • Execute the test and confirm it fails (Red Phase).

Phase 2: Implementation (Green Phase) [checkpoint: 7718a7f]

• Task: Update tracker template to include Calcium
  • Modify templates/tracker.html to add a fourth column to the third row of the "Daily Totals" card.
  • Update existing col-4 classes in that row to col-3 to accommodate the new column.
  • Bind the display to day_totals.calcium with a 0 decimal place filter and "mg" unit.
• Task: Verify implementation
  • Execute the E2E test created in Phase 1 and confirm it passes (Green Phase).
  • Run existing backend tests to ensure no regressions in nutrition calculations.
• Task: Conductor - User Manual Verification 'Implementation' (Protocol in workflow.md)
