2. Tan asymptote unhandled 🐞 Bug ≡ Correctness

handleTrig computes Math.tan(radians) directly; for inputs like 90° (and 90°+k·180°), JavaScript
returns a huge finite number due to floating-point approximation (e.g., tan(90°) ≈ 1.633e16) rather
than an error/undefined.
This produces mathematically incorrect calculator output for common trig edge cases.
Agent Prompt 
## Issue description
`handleTrig('tan')` returns extremely large finite values for angles like 90° because `Math.tan()` at π/2 is dominated by floating-point error. The UI then displays a nonsensical value instead of handling the undefined tangent.

## Issue Context
The code converts degrees to radians and then uses `Math.tan(radians)` directly.

## Fix Focus Areas
- src/App.tsx[76-107]

## Suggested fix
In the `tan` case, add a domain/asymptote check before computing/displaying:
- Compute `const c = Math.cos(radians)` and if `Math.abs(c) < EPS` (e.g., `1e-12`), setDisplay('Error') (or another agreed sentinel) and return.
- Alternatively (or additionally), after computing result, if `!Number.isFinite(result)` or `Math.abs(result) > THRESHOLD`, show an error.

Keep existing clamping for near-0/near-1 if desired.

setDisplay(result.toString());

1. Comment becomes class token 🐞 Bug ≡ Correctness

The Button component includes a CSS-style block comment inside the template-literal for className,
which becomes literal class tokens (e.g., "/*", Chinese text, "*/") on the DOM element.
This pollutes the class list and can make styling/debugging unreliable because these tokens are not
real Tailwind utilities.
Agent Prompt 
## Issue description
A block comment (`/* ... */`) was placed inside a template-literal used for `className`. In JS template literals this becomes literal text and ends up as bogus class tokens in the DOM.

## Issue Context
This occurs in the shared `Button` component, so the bad tokens are applied to many elements.

## Fix Focus Areas
- src/App.tsx[121-138]

## Suggested fix
- Remove the `/* 移动端响应式调整 */` line from the template literal.
- If you want to keep an annotation, place it as a JSX comment *outside* the string, or convert the className construction to something like `clsx(...)` with normal JS comments above the relevant lines.
