/* ============================================================
   cost-tiles.css  -  Costs Phase 2 tile family stylesheet
   ============================================================
   Two tile bodies extending the abstract .pg-section-tile shell
   from components/canonical-render.css (Memory Phase 4.5 Sub-task C):
     .pg-cost-tile-section  per canonical section breakdown
     .pg-cost-tile-tenant   consolidated tenant breakdown

   Each body supports three GENERATIVE-UI-VARIANTS:
     section variants: bar, donut, table
     tenant variants:  stacked, treemap, ranked

   Drift flag pills surface inline on every row:
     confidence  measured / estimate / unknown / hybrid
     scaling     for cost_unit that is not single-event (100_rows, concurrent_connection_month)
     threshold   for threshold-bounded rows (Make.com, Realtime)
     join        for per_action rows whose attribution resolves at viz time

   SECTION-TILE-COMPOSABILITY: every rule below adds a new selector.
   The primitive .pg-section-tile-* family is never overridden.
