/* ══════════════════════════════════════════════════════════════════════
   Agent E — Enterprise Overview tab (Task C2 wiring).
   Additive stylesheet. Does not modify style.css; safe to include as a
   second <link> after style.css (see patches/E_index.html).

   Aesthetic: Claude + Notion baby + ChatGPT + Perplexity parity.
   Accent: Totaly blue #2196F3 only. Yellow #FFEB3B reserved for the
   hologram walkthrough elsewhere in the app and is NOT used here.
   Chart colors: Chart Color Sequence (design-foundations skill) --
   teal #20808D, terra #A84B2F, dark teal #1B474D, light cyan #BCE2E7,
   mauve #944454, gold #FFC553, olive #848456, brown #6E522B.
   No emojis. No markdown italics. No em dashes.

   Design tokens: --tot-* custom properties, aliased to the app's existing
   theme variables (--bg-card, --fg-primary, --fg-secondary, etc. defined
   in style.css's theme blocks) so Overview respects whichever theme
   (dark/light/sepia) is active, with literal fallbacks if those variables
   are unset.
