Was: upper micro-strip (supplements only, scroll) + lower nutrient-strip
(food+supps, expand). Now: ONE strip at top that does both.
Collapsed: horizontal scroll, single row, no wrap.
Tap: expands to full wrap view showing all nutrients.
Tap again: collapses back to scroll row.
Data source: food (product micronutrients on-the-fly) + supplements.
Sorted by % RDI ascending (most deficient first).
Removed: buildMicroStrip() call, .micro-strip element, old scroll handler.
