   Stars Engine — Dark Mode Stylesheet
   Shared by all community landing pages and demo tools.

   Palette:
     bg:        #0d1117  GitHub dark — deep, neutral, easy on eyes in low light
     card:      #161b22  Slightly lifted surface for cards and panels
     text:      #e6edf3  Primary body text — high contrast, readable
     gold:      #d4a853  Accent — amber/gold (occult tools, not corporate blue)
     dim:       #8b949e  Secondary/muted text
     border:    #30363d  Subtle separator, visible but not loud
     green:     #3fb950  Success / confirmed findings
     red:       #f85149  Error / bad news
     blue:      #58a6ff  Links (used sparingly — prefer gold for primary CTA)

   Typography:
     System font stack — fast load, native rendering, no FOUT.
     Georgia for headings on content pages (reads like a book).
     Monospace for code, API examples, source citations.

   Design principles:
     - Dark mode only. These tools are used in low light.
     - Source-cite everything. Citations are credibility.
     - Show, don't tell. Real output over marketing copy.
     - No framework. Single-file HTML, inline everything, fast to load and iterate.
