/* ============================================================
   hopala — blog
   Same design system as index.html (warm paper,
   coral + sage, Fredoka headings, Assistant body). Shared by all
   30 blog pages, so it lives in one cached file rather than inline.

   Logical properties throughout (inline-start/end, not left/right)
   so the Hebrew RTL and English LTR trees use identical rules.
