feat(faq): expanded chemistry glossary + Dr. Flask lab zone

Replaces the compact 3-column table with the full long-form glossary
(Commander + Gemini copy):
- Dr. Flask cover card beside the intro (web-optimized 560px from
  docs/character/drflask-final.png, 1.8MB -> 394KB).
- 'In plain English' callout + the Formulae->...->Lab Notes flow strip.
- 8 term cards (Catalyst Console, re-Agent, Substrate, Formulae, Reactions,
  Compounds, Lab Notes, The Exchange) — chemistry meaning / Corrosion role /
  punchy kicker each.
- Dr. Flask sign-off card with his bio + quips.
- Lab-zone treatment: green accent scoped to .sec--lab so the whole section
  reads as a deliberate 'lab' corner, breaking up the orange brand.

Visually verified via Playwright on the dev server (marketing host): 8 cards,
green theming, Dr. Flask cover + sign-off all render; no page errors.
