feat(marketing): refine global Gapwise product homepage

[andrewmuratov]

Summary

• tighten the global homepage first viewport while preserving the existing Gapwise visual direction
• replace generic feature diagrams with believable timetable, gap-routing, and campus-search product surfaces
• improve the registry-backed university chooser with aliases, campus destinations, accurate derived counts, and accessible states
• restore restrained ecosystem product accents and improve responsive/accessibility polish
• extend site-role browser coverage for first-viewport composition and university search behavior

Validation

• bun run typecheck
• bun run lint (0 errors; existing Fast Refresh warnings only)
• bun run format:check
• bun test (862 passed, 0 failed)
• targeted registry, SEO, marketing, and accessibility tests
• Playwright Chromium project (90 passed)
• bun run build
• bun run security:audit
• node scripts/scan-security-exposure.mjs
• bun run contract:check
• bun run deployment:hobby-budget
• bun run validate:universities
• bun run campus-data:check

Visual verification

Reviewed the production build at 390px, 430px, 768px, 1024px, 1280px, and 1440px+ widths, including full-page desktop/mobile screenshots. No horizontal overflow or console errors were observed. Local WebKit execution is unavailable because the workstation lacks the Playwright WebKit runtime libraries; the CI browser matrix remains authoritative.
