ducoterra baefcde668 fix(web): retire the stale homelab-era copy — neutral, accurate defaults on every page
Fixed: index.html meta description, empty-state sub and composer
placeholder (A1); app/config.py default suggestion chips → the four
neutral A2 defaults (BOR_SUGGESTIONS override unchanged); sources.html
KB page-sub → the current source model (git repos + local dirs +
uploaded archives, Sync pulls/imports); git-sources.html example URL
→ your-repo.git (A3); all 9 footers → neutral default in
span.footer-text (the phase-62 hook); E2E/unit conftests force the
code defaults so a local .env cannot leak corpus copy into tests;
new unit text pins + dedicated E2E suite.

Task 02 verification read-through — no change needed:
- sources.html sync result/error copy (matches the real sync behavior)
- tuning.html page-sub (accurate as written)
- history.html page-sub (accurate as written)
- doc-edit.html page-sub (accurate as written)
- git-sources.html page-sub (accurate as written)
- #sources-gate anonymous copy (accurate as written)

"""Unit: the admin "Sync sources" button contract (phase 32, task 02).
The browser behavior is E2E-covered (tests/e2e/test_sync_button.py,
task 03); here we pin the source-level wiring — the anonymous-safe
ship-hidden button markup, the Sources-page admin reveal on the SAME
cached whoami (no extra fetch), the sync state machine that now lives
in sources.js (owner rework 2026-08-28: the button is Sources-page
only, so the page owns the machine it drives — 2 s poll, 202 start
/ 409 adoption / 403 hide, terminal labels, the "bor:sync-status"
event with the status object as detail, the single-poll-loop guard, no
client-side hard timeout), the page's #sync-result line +
#sync-error-banner, the lazily created error modal (phase 41), and the
§7.4 never-stale CSS (spin + reduced-motion opt-out,
disabled state, 44px floor, contrast pair) — so a silent regression is
caught without a browser.
