/* ============================================================================
   TradeFlow Dashboard CSS
   Component library extracted from /assets/brand/preview.html.

   Imports tokens.css for the source-of-truth palette / typography / radius /
   elevation. Adds: app shell layout, hero band, dark stat tiles, gradient
   avatars, sidebar with gradient accent rail, featured cards, badges, tables,
   tabs, forms, modal, empty / skeleton / progress, utilities.

   See /brand/SKILL.md for usage rules. Five hard rules in short:
     1. Gradient direction fixed: purple-left → green-right.
     2. Gradient is rare and earned — buttons, hero, active nav, wordmark only.
     3. Wordmark appears once per screen (app shell top-left).
     4. Surfaces stay neutral. No tinted card backgrounds.
     5. Teal #3A8487 is the cross-cutting accent.

/* ============================================================================
   Auth-shell family — login / forgot-password / reset-password
   Centered single-card layout with the brand lockup above and a caption below.

   REG 1 (SVG sizing): .tf-auth-mark sets width:64px height:32px here, but
   the auth pages MUST also set width="64" height="32" attributes directly on
   the <svg> element. The inline attributes are the authoritative size when
   this stylesheet is slow to load or cached stale; the CSS rule keeps the
   cascade consistent and lets future redesigns retune the size in one place.

   REG 2 (alert visibility): .tf-alert defines look only (background, color,
   border, padding, typography). It does NOT set display:none. Visibility is
   controlled by inline style="display:none" on the alert div in HTML, and
   toggled via el.style.display='block' / 'none' in JS. This removes the
   dependency on this stylesheet being loaded for alerts to default-hidden.
