Price increase

Quarterly

Plain: Horizon price hike $269→$299/mo + AI credits overhaul + Sidekick assistant now in base plan

Horizon plan price increased from $269/month to $299/month; additional-seat price increased from $89/month to $99/month. AI usage billing metric changed from a 'resolutions' count model (Foundation 50, Horizon 250, Frontier custom; $100 per additional 100 resolutions) to a 'credits' model (Foundation 2,000/mo, Horizon 15,000/mo, Frontier custom credits). Overage pricing is no longer shown as an explicit rate - the comparison table now just says 'Credits apply' instead of '$100/100'.
