 * #350 (browser print): When the user prints the Executive Meetings

 * falls back to a system font that has Arabic glyphs but no GSUB
 * shaping table. The result is Arabic text rendered as isolated,
 * unconnected letterforms — and because the browser then runs the
 * bidi algorithm on those isolated glyphs, the text appears reversed
 * (e.g. "قائمة" prints as "ةمئاق").
 *
 * Fix: in print mode, force every element onto DIN Next LT Arabic
 * (the app's primary Arabic font, which has a full GSUB shaping
 * table). Combined with `font-display: block` in custom-fonts.css
 * and `<link rel="preload">` in index.html, this ensures Chrome
 * never falls back to a system font during the print snapshot. We
 * also explicitly enable common-ligatures and contextual-alternates
 * (`liga`, `calt`) which drive Arabic joining, and pin direction to
 * RTL when the page is in Arabic so Chrome doesn't mis-resolve bidi
 * for cells whose first glyph is Latin.
