Relaunch product site as Launch Control SaaS

[mattyu-dev]

What changed

• rebuilt the canonical homepage as a product-led SaaS launch surface
• replaced the previous coral landing identity with the Launch Control system: Mona Sans, deep plum, lemon actions and fuchsia annotations
• made a readable issue, owner and next action surface the first product proof
• added an accessible tabbed product walkthrough, responsive assets and one consistent Open the workspace conversion path
• aligned the workspace, evidence page, fix lab, social card, 404, README and release metadata
• added Impeccable product and design foundations and bumped the release to 2.2.0

Why

The previous homepage presented the product like a project explanation, split attention across proof and builder framing, and reused a coral action color for both brand and status. The new page positions the product as the pre-launch control layer before Ads Manager and keeps status colors semantic.

Impact

Visitors now understand the product category and workflow in the first viewport, see the actual review decision surface before scrolling and reach the interactive workspace through one consistent action. No customer, ROI, pricing or production claims were added.
