Neutral Borders and Dividers

Borders have very low chroma - they should not compete with content.

|   * Borders should NOT compete with content colors                            |
|   * They exist in the "void" between colored regions                          |
|   * Just enough visibility to separate, never dominate                         |

+---------------------------------------------------------------------------------+
|  MUTED COLORS AND BACKGROUND DESIGN PRINCIPLES                                  |
+---------------------------------------------------------------------------------+
|                                                                                 |
|   1. CONSISTENT MUTED LEVEL                                                    |
|      All muted colors use 80% transparent (20% visible)                       |
|      Creates uniform visual weight across semantic categories                 |
|                                                                                 |
|   2. BACKGROUND ELEVATION PROGRESSION                                           |
|      Each level adds ~2-4% lightness in dark theme                           |
|      Higher elevation = brighter (further from black)                         |
|                                                                                 |
|   3. TEXT ON BACKGROUND CONTEXT                                                |
|      Define text-on-background combinations explicitly                        |
|      Ensures sufficient contrast in all contexts                              |
|                                                                                 |
|   4. NEUTRAL BORDERS                                                           |
|      Border colors have very low chroma (nearly gray)                        |
|      Minimal visual competition with content                                  |
|                                                                                 |
|   5. ADAPTIVE DIVIDERS                                                         |
|      Dividers adapt to theme automatically                                    |
|      Dark theme: light divider | Light theme: dark divider                   |
|                                                                                 |
