/* ParrotPal Label: the light, plain-reading world for parrotpal.com's food and protein guides.
   Built from the UK food label people already read: black ink on white, ruled panels, per-portion tiles,
   protein as the big number in ParrotPal green. Made for older eyes: body text 19px and nothing a visitor reads under 16px (sizes cluster at 16 / 19 / 23 plus display),
   near-black text only (no grey reading copy), state shown by a mark as well as a colour.
   Shared by every label page; page-only styles stay in the page. */
