PR Summary

Medium Risk
Changes the default threshold for incremental overage invoicing, which can alter when customers are charged if OVERAGE_THRESHOLD_DOLLARS isn’t set. The UI change affects chat message rendering by allowing whitespace-only text blocks to display, which could surface new formatting edge cases.

Overview
Updates threshold billing defaults from $50 → $100 across product config and documentation: DEFAULT_OVERAGE_THRESHOLD and env.OVERAGE_THRESHOLD_DOLLARS default are raised, and the docs/FAQ examples are rewritten to match the new trigger.

Fixes a Mothership chat rendering issue by no longer trimming text block content in parseBlocks, allowing whitespace-only deltas to be preserved instead of being dropped.

Greptile Summary

This PR makes two independent fixes: it corrects the whitespace-trimming guard in parseBlocks so that whitespace-only text deltas are no longer silently dropped during streaming, and it updates the overage billing threshold from $50 to $100 across the constants, environment default, and documentation.

Confidence Score: 5/5

Safe to merge — both changes are targeted and low-risk.

The whitespace fix is a one-line guard change with no behavioural side-effects beyond the intended preservation of whitespace deltas. The billing threshold update is applied consistently across the constant, env default, and docs, with no other call-sites left at the old value. No P0 or P1 findings.

No files require special attention.

Important Files Changed

apps/sim/lib/billing/constants.ts	Raises DEFAULT_OVERAGE_THRESHOLD from 50 to 100 to match the updated billing policy.
apps/sim/lib/core/config/env.ts	Raises the default for OVERAGE_THRESHOLD_DOLLARS from 50 to 100, keeping the env default in sync with the constant.
