Edible
Factor

Eating out in Bengaluru means juggling two numbers at once, what a meal costs your body and what it costs your wallet, and no app holds both. On the other side of the table, restaurants run on instinct: no real read on which dishes are healthy, profitable, or even ordered.

Edible Factor closes both gaps from one stack: a diner-facing app that tracks budget and calories together, and an operator OS that turns a menu into something measurable.

The app shipped dark-only. Adding a light theme usually means a second design, and a second set of bugs. Instead it keys off the operating-system preference and flips automatically, while the shipped dark experience stays pixel-identical.

The trick is a token whose dark value equals the original literal. A new --brand-text-strong resolves to pure white in dark and to ink on paper; every white tint became color-mix(var(--brand-text-strong) N%), which is exactly the old value in dark and adapts on light. Four token sweeps, a scoped-cascade fix, a clean production build: dark could not regress, and light came almost for free.
