feat: extend timeline on pure backgrounds

[Bots]

Summary

• extend the landing-page process timeline from three stages to six, carrying concepts through a bounded pilot, published learning, and an explicit next decision
• remove the decorative field grid and contour gradients from every application route
• use exact white for light canvas/card/popover/sidebar surfaces and exact black for dark surfaces
• keep supporting treatments achromatic and reserve exact #ff5a1f for small signal accents
• synchronize browser theme metadata with the exact black/white canvas
• add regression coverage for flat backgrounds, pure surface tokens, theme metadata, and the complete six-stage process

Product behavior

The process now continues through:

1. Shape the concept
2. Test public interest
3. Turn signals into evidence
4. Design a bounded pilot
5. Publish what happened
6. Choose the next move

The final stage explicitly supports refining, repeating, pausing, or archiving rather than implying automatic expansion.

Visual contract

• light canvas/card/popover/sidebar: #ffffff
• dark canvas/card/popover/sidebar: #000000
• supporting surfaces, text, borders, and imagery: grayscale
• sole chromatic accent: opaque #ff5a1f
• no applied background images, field grid, or contour decoration

Verification

• strict RED-GREEN tests observed for the timeline and visual contract
• 190/190 frontend tests
• TypeScript typecheck
• Biome lint and format
• production build
• dependency audit (0 vulnerabilities)
• palette regression tests
• git diff --check
• light and dark desktop browser QA
• 390px mobile screenshot QA
• runtime computed colors: pure white/light and pure black/dark
• runtime computed background images: zero elements
