📝 Walkthrough

Walkthrough

This PR adds an "Accessibility Larger Sizes" toggle to the simulator text-size slider. Text-size categories are split into standard and accessibility sets, with new helper functions for mapping values, indices, and clamping. State wiring and tests are added accordingly.

Changes

Accessibility text-size toggle

Layer / File(s)	Summary
Text-size category constants and helpers packages/serve-sim/src/client/components/simulator-settings-tool.tsx	Adds STANDARD_TEXT_SIZE_CATEGORIES, ACCESSIBILITY_TEXT_SIZE_CATEGORIES, combined TEXT_SIZE_CATEGORIES, MAX_STANDARD_TEXT_SIZE_CATEGORY, and exported helpers isAccessibilityTextSize, textSizeCategories, textSizeIndex, textSizeAfterLargerAccessibilitySizesToggle.
Slider rendering via categories prop packages/serve-sim/src/client/components/simulator-settings-tool.tsx	TextSizeSlider renders ticks from a passed-in categories prop instead of a fixed constant.
Toggle state and UI wiring packages/serve-sim/src/client/components/simulator-settings-tool.tsx	Adds largerAccessibilitySizes state, resets it on refresh, auto-enables it from fetched simulator state, updates queue index translation via activeTextSizeCategories/activeTextSizeIndex, and adds the "Accessibility Larger Sizes" switch with clamped fallback on toggle-off.
Text size control tests packages/serve-sim/src/__tests__/simulator-settings-tool.test.tsx	Adds a new test suite covering category lists, accessibility detection, index mapping, clamping, and toggle-off behavior.
