   Added 2026-09-29. Shared styles for the interactive pieces:
     .mv-*   the orbit model viewer (Stonewall Preserve)
     .sun-*  the sun study
     .ag-*   the art glass composer
     .sk-*   Sketch your Usonian
     .ob-*   the catalog order blank (contact form)
     .lg-*   the logo timeline (Project Timeline page)
   Every value comes from the tokens in style.css and the
   10 · 16 · 26 · 42 · 68 spacing scale. Nothing here touches
   pages that do not load it.
