Offline-first Android livestock ration-balancing studio for smallholders, 4-H families, homestead keepers, and ag-program students. The core loop is a live feed-mill bench—not a farm map and not a chore list: open a fully seeded herd scenario pack (lactating dairy goat, finishing meat sheep, winter beef steer on hay, fiber alpaca maintenance, starter meat-goat kids), drop feedstuffs from a nutrient library into a ration board, watch live crude-protein / energy / calcium–phosphorus balance meters respond, apply seasonal forage packs, run as-fed vs dry-matter math and daily cost, then export a clean ration sheet. Primary UX is scenario cards, filter chips, numeric benches, comparison sheets, and bottom-sheet detail—no drag landscape canvas.

Turn bag labels and hay tests into a defensible daily ration in minutes: species-stage requirements, live nutrient meters, copper and mineral caution flags, and shareable ration sheets—rich educational utility with dense seed packs from first launch.

Key features:
• Six fully seeded herd scenario packs on cold start (dairy-goat peak lactation, meat-sheep finish, winter beef-steer hay ration, alpaca maintenance, meat-goat grower, dry-doe hold) with target weight, stage, and intake assumptions ready to open
• Nutrient ingredient library (grains, oilseeds, hays, silages, minerals, commercial pellets) with crude protein, TDN/ME, NDF, Ca, P, Cu flags, dry-matter %, and editable local price per unit
• Live ration board: add/remove lines, enter lb or kg as-fed, instant toggle to dry-matter basis, auto-sum intake vs suggested DM intake range for the active scenario
• Balance meter strip for protein, energy, Ca:P ratio, and roughage share with clear under/OK/over semantic states and plain-language coaching chips
• Seasonal forage packs (spring mixed pasture, mid-summer drought stretch, mixed-grass hay winter, alfalfa-blend premium) that swap baseline forage in one tap and recalculate the whole board
• Species caution panel: sheep copper sensitivity, urinary-calculus risk on imbalanced grains, abrupt-ration-change warnings, and always-visible educational disclaimer (not veterinary or prescription advice)
• Side-by-side ration compare: clone the board, swap one commodity or forage pack, and read delta meters plus cost-per-day difference before choosing
• Ration sheet export via Android Sharesheet (plain text + formatted summary) for printing or sending to a mentor; Export Preview screen so users see exactly what leaves the device
• Units and defaults center: metric/imperial, currency label, default species, density helpers for scoops-to-weight; all preferences in DataStore
• In-app Settings with full Privacy Policy and Terms of Use screens, offline data statement, export disclosure.
