Challenge: Building a Resilient Dark-Mode Theme Architecture

Consider this architectural challenge:

A popular SaaS analytics platform wants to roll out Dark Mode to its 500,000 daily users. In their initial test, users complained of intense eye strain, confusing dialog overlays, and invisible charts.

Applying our complete color architecture:

1. Replace pure black: Change #000000 canvas to dark slate #0B0F19.
2. Harmonize elevation: Style modals with lighter #1E293B backgrounds and a 1px subtle border (rgba(255,255,255,0.08)).
3. Tone down text halation: Shift primary body copy from pure #FFFFFF to #E2E8F0 (88% opacity white).
4. Chart colors: Recalibrate data visualization lines to lower saturation and higher luminance so they stand out crisply without vibrating.
