/* ============================================================================
   megatrend.css — "taste" theme for Megatrend content pages.
   Reskins the SAME mt-* markup the editorial lessons already emit (so no content
   fragment changes); only the stylesheet swaps. Imports the shared DNA from
   taste-core.css — this file adds ONLY editorial components + a Thai body face
   + the per-trend accent QUARANTINE.

   Taste translation of the NYT/newsprint original:
   - canvas → warm ivory; pure #000 reserved for full-bleed slabs
   - body → Space Grotesk (Latin) + Sarabun (Thai); Playfair italic = rare accent
   - SECTIONING by color-block, not rules: hero / key-players / footer are black slabs
   - per-trend colour QUARANTINED into tiles (stat, term, chart, figure, player tag,
     drop-cap, svg accent) — chrome (links, headings, nav, breadcrumb) stays neutral
   - one shadow, on the floating nav only; every content tile is flat
