Closes #31

Tried on a phone, the whole page scrolled as one. To reach Care, the companion had already left the screen, so a care showed no reaction. Layout only: no new feature, no new art.

Changes

• Fixed stage: the companion, its wish and its bond stick right under the game bar. The bar already keeps the coins in view. The options scroll under the stage, with no gap for them to show through.
• Order: Care, Animals, Colours, Clothes.
• Sliding rows: each section is one row that slides sideways, card by card. It works with a finger, with the keyboard (focus scrolls), or with a mouse wheel while the row can still move. The three clothes rows stay apart. Right to left in Persian.
• The wish bubble floats over the card and hides after 4 s. Tapping the companion (or Enter) shows it again, and so does fulfilling it. Hiding it never changes the wish or moves the companion.
• A smaller companion on screens under 600 px high; no transition under reduced motion.
