Real large-application source now crosses more router, query, layout, data, authentication, and authoring boundaries without adding React, hydration, or package runtimes.

LARGE-APP MIGRATION

Specialize common source.
Keep boundaries explicit.

ROUTES

Fold exact matches

Build-known useMatch and native route shells add no browser router.

QUERY

Own URL state

Numeric and imported-string fallbacks remain reactive through native search signals.

LAYOUT

Erase grid wrappers

React Bootstrap Row and Col become native Bootstrap markup.

DATA

Replace package queries

Owned effects preserve loading, errors, stale isolation, and keyed data.

AUTH

Intake session ownership

Build evidence covers storage, login, restore, protected reads, and 401 clearing through existing state semantics.

LIMITS

Fail honestly

Runtime i18n and unproven package surfaces retain actionable diagnostics.

UPGRADE

Expand migration coverage without expanding the runtime.
