Bootstrap + custom CSS baseline

A customer pipeline page before migration.

This page uses Bootstrap grid, cards, badges, buttons, and tables with several product-specific CSS overrides. It is a closer match to the messy middle of real migrations than a single button example.

What this version demonstrates

Bootstrap is fast, but local overrides become the migration surface.

The custom CSS above represents the design decisions that must be preserved: brand color, rounded cards, soft shadows, responsive spacing, and status treatments.

Keep the markup map

List Bootstrap components before rewriting classes.

Extract design tokens

Move repeated colors, radii, and shadows into Tailwind config.

Migrate by section

Convert navigation, hero, cards, and tables separately.

Verify responsive behavior

Compare breakpoints and interaction states before removing Bootstrap.
