USER PROFILES (/forum/user/[username]):
- New API at /api/forum/user-by-username/[username] resolves by
username OR display_name (URL-encoded), since forum threads/replies
store author_name = display_name. Returns the persona's profile,
thread history (up to 50), and recent replies (up to 20).
- New page renders the persona card with archetype badge
(Audio Engineer / Colorist / etc.) + expertise level badge
(beginner/intermediate/senior) + role title, company, location,
years_experience, join date, and an expertise-tags chip row.
- Two columns underneath: "Threads started" and "Recent replies"
with proper deep-links into each thread.
- Author names in /forum, /forum/[slug], and /forum/thread/[id] are
now <Link> elements pointing to /forum/user/<displayname>, with
onClick=stopPropagation so the card-level click handler doesn't
also fire.
FAVICON:
- Hand-built neon pulse waveform — emerald→cyan→purple gradient on
dark navy background, designed to read at 16×16 to 256×256.
- Multi-resolution favicon.ico (16/32/48/64) + SVG + PNGs at
16/32/48/64/96/192/256 under /static/favicons/.
- layout.tsx icons block now references all sizes including the
apple-touch sizes (192, 256).
No env / DB changes here — pure deploy.
