/* ==========================================================
   Thresca — brand identity case study
   Same structural system as sarthi.css (type sizes, spacing, card
   pattern, reveal/split animation) so every case study page reads
   consistently. Only the brand accent values below are Thresca's own.

   Font: Antonia H1, self-hosted below across all 7 weights (Light 300
   through Black 900, each with an italic), used ONLY in the type-weight
   slider demo (.th-sample-text / .th-aa) — same scoping as Aquire on
   AuraWear. Every other headline on the page uses Sora, the site's own
   display font, via --font-display-alt below.
