- Store opens with two choices (subscription / question packs); 3- and 6-month cards
show per-month price and saving.
- Units that need a subscription show a crown badge and open the store; a 402 from
the quiz goes there too. «ادامه بده» skips locked units.
- Profile: subscription card with an animated days-left bar (planDurationDays).
- BrandMark (SVG) on splash, home header and footer; copyright footer; floating math
glyphs on splash. CSS transform/opacity only; honours reduced motion.
