- Columns dynamically include only stores that returned data
- Sticky model column (left) — scrolls horizontally on mobile
- Best price per row highlighted: green bg + ✓ badge + green text

- 'Мин' column on far right — explicit cheapest price summary
CSS:
- .report-matrix-wrap with rounded card

UX:
- User can now visually compare 'where is it cheapest' at a glance
