fix(web): remove glass chrome strip below chat composer

[maria-rcks]

What Changed

Removed the glass chrome strip that rendered below the chat composer: the empty chat-composer-lower-chrome div and the chat-composer-shared-blur backdrop layer, plus their now-dead CSS rules. The composer overlay keeps the same bottom spacing via its own padding, and the composer's floating-glass-surface is unchanged.

Why

The strip appeared as a second glass box leaking out under the input, instead of the composer floating on its own. Deleting the two decorative elements and folding their shared background values into the surviving .floating-glass-surface selectors fixes it with a net −29 line diff and no behavior change to the input itself.

Note

Low Risk
Visual/layout-only chat composer chrome cleanup with no logic or API changes; minor risk of bottom spacing differences on devices with safe-area insets.

Overview
Fixes a second glass panel appearing under the chat input by removing the decorative backdrop layer (chat-composer-shared-blur) and the empty chat-composer-lower-chrome spacer from ChatView.

Bottom safe-area padding now lives on the composer overlay wrapper instead of the removed lower chrome, so timeline inset / composerOverlayHeight behavior should stay aligned. floating-glass-surface on ChatComposer is unchanged; related CSS is trimmed so glass styles apply only to that class (no shared rules with the deleted chrome).

Note

Remove glass chrome strip below chat composer

Removes the lower chrome divider and shared blur wrapper elements from the chat composer in ChatView.tsx. Safe-area bottom padding is now applied directly on the composer overlay wrapper. Corresponding CSS classes chat-composer-lower-chrome and chat-composer-shared-blur are deleted from index.css, with glass styling consolidated onto .floating-glass-surface only.

Bottom safe-area taps hit timeline

Medium Severity

Bottom spacing moved onto the pointer-events-none composer overlay, but the removed chat-composer-lower-chrome sibling was the only in-flow layer in that band with default pointer hit-testing. Taps in the safe-area and extra bottom padding can reach the scrolling timeline underneath instead of being absorbed above it.

Approvability

Verdict: Needs human review

This UI cleanup removes a glass effect below the chat composer. However, an unresolved review comment flags a potential pointer-events issue where taps in the bottom safe-area may now pass through to the timeline underneath, which warrants human verification.
