Apply Prism design system — brass/ink palette, EB Garamond + IBM Plex typography

Implements the design kit: champagne brass accent (#C2AA7A), deep midnight
backgrounds, EB Garamond italic headings, IBM Plex Sans/Mono body and numbers,
terminal-density KPI cards, restyled sidebar brand mark, flat pill tabs, and a
global Plotly theme so all charts inherit the dark palette automatically.
