This PR addresses layout and padding issues that were occurring on smaller screens, like mobile phones

What was wrong? A fixed-position element (text area component) was causing problems with how other elements were spaced and positioned, making the UI look a bit off on small devices

What's changed? I've adjusted the fixed-position element and made other necessary tweaks to ensure everything now fits and looks correct on smaller screens

Walkthrough

This update modifies the layout and styling of several frontend components related to chat functionality, adjusting container classes, element positions, and scroll behavior for improved structure and appearance. Additionally, a new pnpm-workspace.yaml file is introduced to manage build dependencies by specifying ignored and exclusive packages.

Changes

Cohort / File(s) Change Summary
Chat Layout Structure
frontend/components/Chat.tsx
Reorganized JSX structure by moving theme toggler and toggle button above the main element, adjusted container classes for full viewport height and overflow, and updated main element to remove max-width and padding constraints.
Chat Input Positioning
frontend/components/ChatInput.tsx
Changed chat input container from fixed to absolute positioning, added horizontal padding, centering, shadow, and border styling to container and wrapper.
Messages Section Layout
frontend/components/Messages.tsx
Updated section to full viewport height with scroll, added new wrapper div for padding and border, and adjusted flex layout and spacing. Message rendering logic remains unchanged.
Build Dependency Configuration
pnpm-workspace.yaml
Introduced configuration file specifying packages to ignore (sharp, unrs-resolver, workerd) and packages to exclusively build (@tailwindcss/oxide, esbuild).

Poem

A bunny hopped through lines of code,
Shifting buttons, borders showed.
Messages now scroll with grace,
The chat input found a brand new place.
With workspace rules so neat and trim,
This fluffy dev is filled with vim!

29-34: Conflicting height declarations

The element sets both h-screen (100 vh) and an inline style height: calc(100vh - 10rem).
Inline style wins, but keeping both is confusing and hurts maintainability. Pick one source of truth (prefer Tailwind via a custom utility).

135-136: Centering tweak looks off

md:left-1/2 md:-translate-x-[51%] overshoots centre by 1 %. Unless compensating for scrollbar width, use the standard combo left-1/2 -translate-x-1/2 to avoid magic numbers.

6-8: Verify interplay of onlyBuiltDependencies

When onlyBuiltDependencies is set, pnpm will build only the packages in this list (@tailwindcss/oxide, esbuild) and ignore every other native dep, making never/ignoredBuiltDependencies redundant. Confirm this is the intended behaviour; otherwise remove one list to avoid confusion.

72-90: Check side-effects of overflow-hidden on the root container

With overflow-hidden any absolutely-positioned element that extends outside the main area (e.g. ChatInput shadow, toast portals) will be clipped on mobile. Ensure this does not regress visual polish or accessibility (e.g. focus ring outlines).

⚠️ Potential issue

Broken Tailwind class px-

The class list contains px- without a value, producing no CSS and failing Tailwind’s parser in strict mode.
Replace with a concrete spacing value, e.g. px-4.

-<div className="absolute w-full px- max-w-3xl ...
+<div className="absolute w-full px-4 max-w-3xl ...
🤖 Prompt for AI Agents
In frontend/components/ChatInput.tsx around lines 135 to 136, the Tailwind class
list includes an incomplete class `px-` which is invalid and causes Tailwind's
parser to fail. Replace `px-` with a valid padding-x value such as `px-4` or
another appropriate spacing value to fix the issue.

⚠️ Potential issue

Non-standard Tailwind spacing utilities

Classes pb-18 and md:pb-22 are outside Tailwind’s default spacing scale (0…96).
If these values are not added in the project theme, they will be purged and no CSS will be emitted, leaving the bottom padding missing on small devices—the very issue this PR tries to fix.

🤖 Prompt for AI Agents
In frontend/components/Messages.tsx around lines 30 to 35, the padding-bottom
classes pb-18 and md:pb-22 use non-standard Tailwind spacing values that may be
purged if not defined in the theme. Replace these with valid Tailwind spacing
utilities within the default scale (e.g., pb-16 or pb-20) or add custom spacing
values to the Tailwind config if needed, ensuring the bottom padding is applied
correctly on all devices.

🛠️ Refactor suggestion

ignoredBuiltDependencies is not a recognised pnpm key

pnpm expects the key to be neverBuiltDependencies; using an unknown key means the listed packages (sharp, unrs-resolver, workerd) will still be built.
Rename the key to avoid a silent mis-configuration.

🤖 Prompt for AI Agents
In pnpm-workspace.yaml at lines 1 to 4, the key `ignoredBuiltDependencies` is
incorrect and should be renamed to `neverBuiltDependencies` to ensure pnpm
properly recognizes and skips building the listed packages. Replace
`ignoredBuiltDependencies` with `neverBuiltDependencies` to fix the
configuration.
