Stellar-flavored stealth-flow diagrams

Type: design / docs

Context

The existing SVG diagrams in docs/assets/diagrams/ (stealth-flow.svg, stealth-visual-flow.svg, key-derivation.svg, etc.) are EVM-centric — they show hex addresses, secp256k1 math, and 0x... prefixes. A Stellar-first reader has to mentally translate to StrKey, ledger sequences, and ed25519.

We want a parallel set of Stellar-native diagrams.

Scope

Create the following SVGs and add them to docs/assets/diagrams/stellar/:

1. stealth-flow-stellar.svg — sender → ECDH → stealth address (StrKey) → announcement (Soroban event) → recipient scan
2. key-derivation-stellar.svg — signature → SHA-256 + domain separation → spending scalar / viewing scalar → public keys
3. view-tag-scan-stellar.svg — incoming announcements, view tag filter, ECDH only on matches
4. name-resolution-stellar.svg — alice.wraith → SHA-256(name) → wraith-names contract lookup → meta-address
5. fee-bump-withdrawal-stellar.svg — stealth account with no XLM → sponsor's outer tx → inner withdraw → resulting state

Style guide

• Match the existing diagram aesthetic (dark-monochrome, hand-drawn-ish, minimal).
• Use StrKey-shaped addresses (G... or C... for contracts) in examples.
• Annotate with Stellar-native terms (ledger, contract ID, Soroban event topic).
• Keep file size reasonable (no embedded raster, no megabyte SVGs).

Where to add references

Update the following MDX files to link to the new diagrams:

• docs/sdk/chains/stellar.mdx
• docs/architecture/overview.mdx (Stellar paragraph)
• docs/architecture/stellar-cryptography.mdx (if #03 lands)
• docs/guides/stellar-quickstart.mdx (if #01 lands)

Acceptance criteria

• 5 new SVGs committed.
• Each one referenced from at least one MDX page.
• Light/dark mode rendering verified (Mintlify auto-inverts colors for some SVG patterns — sanity check).
• Source files (Figma / Pencil / SVG editor of choice) committed alongside if not directly editable.

Why this matters

Visual learners are a non-trivial slice of every dev audience. Stellar developers especially have grown up with very specific iconography (Horizon, Soroban, Stellar branding) — meeting them there matters.
