feat(donate): rewrite donation page with tier structure and mission framing

[TimeToBuildBob]

Updates the donation page per the Experiment 1 plan from ErikBjare/bob#336.

Changes:

• Replace flat 'thanks' page with three-tier structure: Supporter ($5/mo), Champion ($25+ one-time), Believer ($50/yr)
• Lead with privacy-first mission framing (Variant A/C hybrid)
• Add 'Why donate' and 'Where does the money go' sections
• Reorder donation methods
• Keep existing crypto addresses and Patreon options

Baseline (from Open Collective, last 30 days):

• 4 contributions, $274.67 total
• 44 lifetime contributors, $8,465 all-time

Greptile Summary

This PR rewrites donate.md to replace the old flat "thanks for donating" page with a structured three-tier layout (Supporter/Champion/Believer), adds mission/rationale sections, and updates the donation Methods section with explicit fee comparisons for most platforms.

• Tier structure: Three named tiers with amounts and sponsor-page listing promises are added above the fold; the old page had no tier concept.
• Methods section: Fee detail is now explicit for Liberapay (0%) and Open Collective (10%); GitHub Sponsors correctly calls out the 10% Open Collective backend fee; Patreon still uses vague "platform fees apply" unlike the other entries.
• Sponsors-page promises: All three tiers promise sponsors-page listing, but the existing sponsors page has a $10 total-donation floor and no tier-based "special recognition" column, creating a gap between the copy and the current implementation.

Confidence Score: 5/5

Safe to merge — this is a content-only rewrite of a single markdown page with no functional code changes.

The change is entirely copy and structure on a static marketing page. No application logic, data, or configuration is touched. The open items (sponsors-page listing threshold, Believer special-recognition, Patreon fee vagueness) are content accuracy concerns that can be addressed in follow-up without risk.

No files require special attention beyond the content accuracy gaps noted in donate.md.

Addressed both Greptile P1 findings in the latest commit:

• 3-year tier removed: $120/3-year dropped from the Believer tier — none of our listed platforms support multi-year subscriptions, so advertising it was a broken user flow. Now just $50/year.
• Sponsors-page recognition restored for all tiers: The old page promised all donors would be listed on /sponsors/. That promise was silently missing from Supporter and Champion in this rewrite. Added it back to both, with Believers still called out for "special recognition".

[TimeToBuildBob]

Follow-up commit addresses the remaining Greptile findings:

• Methods reordered: Liberapay (0% fee) is now listed first, restoring the old page's preference order. Open Collective (10%) moved down.
• GitHub Sponsors fee disclosure restored: Added the Open Collective fee caveat back — "backed by Open Collective, so their 10% fee may apply" — which the old page had but the rewrite dropped.

[TimeToBuildBob]

Fixed the remaining Greptile P1/P2 findings (commit 9eca103):

• GitHub Sponsors fee: "may apply" → "applies" — the OC 10% fee always applies on this path, not conditionally
• Patreon fee disclosure: Added "(platform fees apply)" — Patreon charges creators 5–12% depending on plan plus payment processing; exact % varies by plan so this is the honest phrasing

[TimeToBuildBob]

Friendly bump — this PR is 19 days old with no reviews.

Self-review recheck (2026-05-19):

• Diff is still clean: 37+ 33- LOC, single file (donate.md)
• Copy reads well — tier structure is clear, mission framing is on-point, donation methods are properly reordered
• No code changes, so no build/test concerns

This is the simplest PR in the current ActivityWatch queue. Would appreciate a review when you have a moment.

Addressed Erik's requested changes in 40b12f68 and replied inline on each thread.

Current state:

• Transparency wording is narrowed to Open Collective-routed donations
• The funding examples now mention Kerkko/Brayo plus out-of-pocket coverage when donations were short
• The BTC/ETH wallet-location HTML comments are restored

All review threads show as resolved on my side. Please take another look when you have a moment.
