docs(character): add Dr. Flask model sheet + sync bible to the board

invideo produced a full character design board (turnarounds, 8-expression
progression, micro-expressions, postures, bubble-hand gestures, silhouettes,
color palette). Committed as the definitive reference and folded its details
(palette, expression/posture/gesture lists, character note) into the bible.

-## Design notes (invideo storyboard)
+**Character note (from the board):** *Bubbles faster when excited. Professional
+yet playful. Expert in chemical catalysts.*
 
-A fully storyboarded character, not a static sticker:
+## Color palette
 
-- **Face:** expressions + micro-expressions; kawaii-friendly, approachable.
-- **Head detail:** mortarboard cap with tassel; the flask body is the head/body.
-- **Posture & silhouette:** distinct, readable poses for the explainer beats.
-- **Hands/gestures:** formed from **bubbles** — gesturing while he narrates.
-- **Liquid:** neon-green, lightly bubbling (the "more bubbling" payoff).

-Dr. Flask's neon green is the canonical reason the **chemistry FAQ section is a
-"lab zone."** That section overrides the brand's rust-orange accent with a green
-set (`--accent-text: #5bd183`, scoped to `.sec--lab`) so Dr. Flask reads native
-to his corner. Green elsewhere on the site is still a clash — it is intentional
-*only* in the chemistry glossary.
+**In-product note:** the FAQ "lab zone" UI accent is a *readable* green
+(`--accent-text: #5bd183`, scoped to `.sec--lab`) — same family as the liquid
+but toned down so text/borders stay legible on dark (pure `#00FF3D` vibrates as
+UI text). Character art uses the neon greens above; UI uses the readable
+derivative. Can nudge the UI green brighter toward canon on request.
