Save Tool v1.8.3 - light theme by default + auto-scroll to new downloads

Light by default (Claude-style), and the download card comes to you

Two changes you asked for:

1. The page now opens in the light cream theme (like claude.ai), instead of following your phone's dark mode. There is a moon/sun button in the top-right corner if you want dark back - your choice is remembered per device.

2. After you paste a link, the page scrolls to the new download card automatically. Previously the card appeared below the fold and it looked like nothing was happening.

Verified in a real 390x844 phone viewport: default background is cream (rgb(250,249,245)), the toggle switches and survives reload, and submitting a link scrolls the new card into view (scrollY 0 -> 293, card top at 342px).
