   Project Taste — tools.css
   Shared, reusable UI primitives used INSIDE tool pages. Styling these once
   means every tool (present and future) inherits a consistent premium look.

   Consumes tokens from theme.css. Load after components.css.

   Contents:
     1. Field wrapper + label hints
     2. Segmented control (mode switch)
     3. Inline checkboxes / radios
     4. Dropzone (file upload area)
     5. File preview (image + metadata)
     6. Split / two-column tool layout (input | output)
     7. Small helpers (code output, stat chips, copy-inline)
