/* Consist brand dark theme, layered on top of Bootstrap 5 (see base.html
   for the CDN links) which is already running in `data-bs-theme="dark"`.
   Bootstrap's dark palette handles most components (forms, cards, borders,
   muted text, alerts) automatically -- see CLAUDE.md "Frontend" section
   for which components need a manual override and why (short version:
   Bootstrap's *compiled* CSS bakes literal colors into brand-colored
   components like .btn-primary rather than reading the shared
   --bs-primary token, so those specific ones are re-pointed here).

   Visual language as of the "calmer" pass: Inter at medium weight (500/600)
   rather than heavy display type, flat bordered surfaces (no blur/glass,
   no glow), tighter corner radii -- editorial/restrained rather than bold
   marketing-gradient. See CHANGELOG "Unreleased" for what this replaced. */

/* Both supplied partner assets are dark artwork meant for light backgrounds
   (cisco-logo.svg is brand blue #049fd9, splunk-logo.webp a near-black
   wordmark), so on this dark ground they'd be almost invisible as-is.
   brightness(0) invert(1) flattens each to a clean white wordmark -- the same
   trick the Consist header logo uses, and the usual treatment for a partner
   row on a dark surface. Swap in official white/reversed assets if Marketing
   has them and this filter can go away.

   cisco-logo.svg shipped with ~100px of transparent margin on every side of a
   560x400 canvas; its viewBox is cropped to the artwork (360x190) so `height`
   means the same thing for both files. The two are still tuned separately by a
   few px because Splunk's asset is a two-line lockup ("splunk>" plus "a CISCO
   company") while Cisco's is a single compact mark -- matched optically, not
   numerically. */
