30.6.4 Asymptotes: Hugging Close but Never Touching

Core idea

The farther the curve reaches, the closer it hugs the two slanted lines y=±(b/a)x, like rails it approaches forever without meeting.

Module goal. Introduce the hyperbola from the constant difference of distances to two fixed points, and master its standard equation, asymptotes, and eccentricity.
