/* ==========================================================================
   Vigilia landing page
   Implemented from the "Vigilia Landing" design canvas.

   The page ships every string in both English and Arabic. Each localised
   block carries data-lang="en" or data-lang="ar"; the rule under "Language
   gate" hides the inactive one. Typographic differences between the two
   scripts (weight, size, line-height, letter-spacing, the mono/Arabic swap
   on labels) live in html[lang="ar"] overrides next to their base rule
   rather than in a duplicated Arabic stylesheet.
