Annotate hardcoded branding touchpoints with TODO: BRANDING markers

[yarikoptic]

Summary

• Annotate every hardcoded branding touchpoint in the codebase with TODO: BRANDING markers (29 files, comments only, zero behavior change)
• Split annotations into two groups for phased resolution:
  • BRANDING(name) (20 spots): pure "DANDI" → instance name substitutions, fixable with existing settings.DANDI_INSTANCE_NAME / instanceStore.instanceName
  • BRANDING / BRANDING START/END (23 spots): require new branding config (logos, colors, URLs, funding text, support emails, etc.)
• Add doc/design/branding.md with full inventory, annotation conventions, and analysis of the EMBER archive fork (git diff origin/master...gh-aplbrain/prod)
• Add minimal "Branding Annotations" section to DEVELOPMENT.md pointing to the design doc

Dependencies

This is a documentation/annotation-only PR — no code behavior changes.

However, the next step (resolving BRANDING(name) items) depends on

• Replace hardcoded DANDI identifiers with dynamic instance config #2765

being merged first, since that PR introduces the frontend instanceStore that BRANDING(name) fixes will use. Planned sequence:

1. This PR: annotate all branding touchpoints and provides design doc/comparison against EMBER
2. ⏳ PR Replace hardcoded DANDI identifiers with dynamic instance config #2765: merge vendorization fixes (instanceName/instanceIdentifier dynamic in citations, HowToCite, etc.) for frontend
3. Next PR: resolve all BRANDING(name) items using existing vendorization variables
4. Future: design and implement new branding config for remaining BRANDING items (logos, URLs, colors, etc.)

How to find annotations

# All branding touchpoints
git grep "TODO: BRANDING"

# Only Group 1 (name substitution — easy wins)
git grep "BRANDING(name)"

# Only Group 2 (needs new config)
git grep "TODO: BRANDING" | grep -v "BRANDING(name)"

Test plan

• Verify no behavior changes — this is comments-only, CI should remain green!
• Review doc/design/branding.md for completeness against EMBER fork diff
• attn: @dandi/ember please complement with what additional aspects to potentially bring in right away . Feel welcome to propose PR to annotate those places!
