Summary

The red outline drew attention to cards that aren't the main thing on the page.

• homeCard(tint:thin:) gains a thin option: 1pt light / 1.5pt dark, versus 1.5 / 2 for the red cards.
• Food page: the Nutrition Facts and Ingredients cards switch to gray + thin. The calorie hero card and the blue/green/orange macro cards keep their color.
• Profile page: its three gray card styles become thin, so their outlines match the weight elsewhere.

Test plan
