Subject: [PATCH] Fix B9 and Se showing 0%: unit mismatch mg vs mcg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

B9 (folate) label said "мкг" but packaging shows "мг" — user entered
0.4 mg, DB stored 0.4 mcg, 0.4/200 = 0%. Fixed: label says "мг",
mult:1000 converts to mcg on save, back to mg on display.
Same for selenium: packaging uses mg, DB uses mcg.

Beta-carotene showing 0% is correct — Daily Men supplement contains
retinol acetate (vit A), not beta-carotene. They are different forms.
