/* ════════════════════════════════════════════════════════════════════════
   PHASE 4 — INVOICE CLASSIFICATION UI
   ════════════════════════════════════════════════════════════════════════
   Styles for /SalesAnalytics/InvoiceClassification.

   Builds on:
     - sa-shared.css         → tokens (--accent, --text-muted, etc.),
                               primitives (.sa-card, .sa-btn, .sa-pill,
                               .sa-toast), modal shell
     - sales-analytics-phase1.css
                             → .sa-divisions-toolbar (flex row),
                               .sa-classify-toggle, .sa-classify-actionbar,
                               .sa-classify-btn (action bar buttons),
                               .sa-row-checkbox, .sa-bulk-strip-suggest*
                               (suggestion label sub-elements)

   Owns (new selectors):
     - .sa-subline                       headline explainer paragraph
     - .sa-queue-summary                 toolbar count line
     - .sa-vendor-groups / -group        per-vendor <details> shell
     - .sa-vendor-summary / -name /
       -meta / -unclassified-count       header inside each <details>
     - .sa-vendor-group-done /
       .sa-vendor-done-badge             post-classify visual state
     - .sa-bulk-strip-prompt /
       .sa-bulk-strip-kind /
       .sa-bulk-strip-kind-suggested     three new bulk action buttons
     - .sa-invoice-item-list / -row /
       -name / -code / -meta             queue row layout
     - .sa-suggestion-slot /
       .sa-suggestion-pill +
       -retail / -ingredient /
       -operational                      per-row suggestion pills
     - .sa-row-hidden /
       .sa-show-more-btn                 vendor row expander
     - --sa-checkbox-col on
       .sa-invoice-classify-card         own checkbox column variable
                                         (mirrors Phase 1's pattern)

   Color encoding for the three kinds, consistent across pills + hovers:
     Retail       → accent blue   (matches Phase 1 retail panel)
     Ingredient   → emerald green (matches Phase 1 meal panel — invoice
                                   has no Meal kind so no collision)
     Operational  → neutral gray  (consistent with Phase 1 excluded)
