What does Toyota's TNGA architecture mean?

Architecture involves aspects such as research and development, spare parts, and production. Simply put, the TNGA architecture is a set of standards or concepts for research and development, production, and manufacturing. Below is an introduction about Toyota: Introduction: Toyota Motor Corporation is an automobile manufacturing company founded by Kiichiro Toyoda in September 1933 and officially established on August 28, 1937. Affiliates: Toyota is the first automaker to achieve an annual production volume of over 10 million vehicles and is also the parent company of the Lexus and Subaru brands, as well as the largest shareholder of Fuji Heavy Industries. Logo: This logo was released in October 1989, on the occasion of Toyota's 50th anniversary. The design focuses on a symmetrical composition of ellipses. The ellipse, a curve with two centers, symbolizes the heart-to-heart connection between the automaker and its customers.
When I worked on production line planning at an OEM, I had exposure to TNGA, which is essentially Toyota's manufacturing revolution. Not only did the commonality rate of chassis components increase to 70%, but even small parts like the steering wheel and steering column were standardized. The most impressive part is that body rigidity improved by up to 65% compared to the old platform—just look at the eighth-gen Camry, which uses 1500MPa hot-stamped steel for the A-pillar and swapped the rear suspension from a 'chopstick' setup to a double-wishbone. Last time I test-drove the Avalon, its center of gravity was lowered by 15mm, making cornering stability uncharacteristically Toyota-like. Now even the Lexus ES uses the TNGA-K platform, and during maintenance, I noticed the engine bay layout is identical to the Camry's.
