Improved
A dedicated step for each product category. In the step-by-step form, products are now split across their own steps by category, in the order from your inventory. Categories without products are skipped. That way each step only shows what belongs together.
A clear grid instead of sideways scrolling. Product cards now sit side by side and below one another in a grid that adapts to the screen width. The sideways scrolling that cut off cards at the edge is gone.
Fixed
Prices in the summary are calculated correctly. For products priced per guest or per hour, the summary only showed the unit price as the total. It now scales correctly by the number of guests or hours, and each line shows the multiplier (for example "× 16 guests").
The guest field starts empty. The guest-count field came pre-filled with a number you had to delete before typing. It now starts empty with a placeholder; if the value is missing when you continue, a hint appears.
Only one total is shown. The total was displayed twice in the summary. It now appears in exactly one place.
Unnecessary subtitles removed. Small subtitles above the steps that added no value have been removed.
