/* MAV FIELD PORTAL — shell styles.
 *
 * Written for one hand, a glove, and direct sun on a truck deck.
 *   - Every interactive target is >= 48px; primary actions are 56px.
 *   - Nothing is hover-only. Hover does not exist on a phone.
 *   - Default palette is LIGHT + high contrast, because a phone in sunlight is
 *     more readable dark-on-light at full brightness. A night palette is one
 *     tap away for inside a dark plant, and is remembered.
 *   - Redacted fields render as the word "hidden", never as 0. A withheld number
 *     that looks like a zero is how somebody quotes a job wrong.
 *   - `stated` values (someone said it) get a dotted underline + a "heard" chip
 *     so they never read identically to a measured one.
