/* ===========================================================================
   Billing - pricing section, credits upsell, payment success.

   The pricing section's structure, the animated monthly/annual toggle, the
   cursor-follow card glow and the attention-pulse hint are ported from
   ../thesisai's landing.css (.pricing-section / .pc-*), then restyled onto
   siriusly's dark orange/black tokens. thesisai inverts its "Pro" card to dark
   on a light page; siriusly is already dark, so the featured card inverts the
   other way - a warm orange-lit surface against the coal cards.

   bl- classes below are the standalone billing pages (credits, success).
