/**
 * Base input primitive.
 *
 * v1.4 hardening: defaults `autoComplete` to `"off"` and tells
 * LastPass / 1Password to skip the field when the caller does not
 * opt in to a semantic autocomplete value. HealthLog is a health-data
 * app — letting browsers / password managers autofill measurement,
 * medication, mood, and AI-token inputs with the user's last-saved
 * email or account password is at best confusing and at worst leaks
 * credentials into a free-text field that gets persisted server-side.
 *
 * Auth and profile forms (login, register, change-email) keep working
 * because they already pass an explicit `autoComplete` value —
 * `"username"`, `"email"`, `"current-password"`, `"new-password"`. When
 * `autoComplete` is anything other than `"off"`, the LastPass /
 * 1Password / Bitwarden ignore attrs are dropped so password managers
 * fill the field normally.
 *
 * v1.25.11 — extend the cross-manager opt-out to Bitwarden
 * (`data-bwignore`) alongside the existing LastPass (`data-lpignore`)
 * and 1Password (`data-1p-ignore`) hints, so config / secret fields
 * (AI keys, bearer tokens, integration secrets, webhook URLs) are not
 * offered for autofill or saved as a login by any of the three.
 *
 * v1.4.27 mobile pass: derive a sensible `inputMode` default from the
 * `type` prop so every numeric / email / tel / url / search field
 * surfaces the right on-screen keyboard on iOS Safari and Android
 * Chrome without each call site having to repeat the attribute. Most
 * `type="number"` fields in HealthLog accept decimals (kg, mmol/L,
 * sleep hours), so the default is `"decimal"`; integer-only call
 * sites can still pass `inputMode="numeric"` explicitly.
