034: apply default layout to all pages + cream brand palette

Two fixes:

1. Inner pages were rendering with NO theme (raw HTML, no sidebar, no
   header CSS). Just the Docs only auto-applies its layout if pages
   declare 'layout: default' or a Jekyll defaults block sets it. Add
   the defaults block in _config.yml so every page gets the theme
   layout without per-file frontmatter changes.

2. Tune the color scheme to match the SPECTRA banner: cream content
   background (#fbf7ec), navy sidebar (#16213e), teal links and
   accents. Adds warm orange variable for future use.
