8.3.2 Final logomark approval (brand-designer / founder decision)

Type: decision · Executor: human · The logomark is a creative artifact — the buildable default from 8.3.1 needs a human brand/founder sign-off (or a substituted glyph from a designer) before it propagates across the app, favicon, and OG images.

Review the 8.3.1 mark + lockup system. Either ratify the default mark or supply the final glyph (SVG). Once approved, the mark feeds 8.3.5 (application) and 8.3.7 (root OG).

Acceptance criteria

• The final logomark SVG is approved/supplied; wordmark + lockup confirmed.
• Decision recorded (which mark, any tweaks) as a comment so 8.3.5/8.3.7 build the right asset.

No PR — type: decision, marked done on the user's confirmation.
