THE BOARD, STATE BY STATE
==========================================================

Thirteen states and an empty plate. Every frame is identical except the words
and the light, so the animation is a CROP between them.

The light is on the LEG when Manan speaks and on the HEAD when Viveka answers.
From state nine the light stays on the head, because from there they agree.

----------------------------------------------------------

01  MANAN    light on the LEG
    BOARD SAYS   FATIGUE IS IN THE MUSCLE
    CREDIT       A. V. HILL, 1923
    SPOKEN       In 1923 a physiologist called A. V. Hill put runners on a treadmill and measured everything they did. He decided fatigue happens in the muscle.

02  VIVEKA   light on the HEAD
    BOARD SAYS   FATIGUE IS IN THE BRAIN
    CREDIT       TIM NOAKES, 1997
    SPOKEN       It does not. In 1997 Tim Noakes said it happens in the brain.

03  MANAN    light on the LEG
    BOARD SAYS   THE OXYGEN RUNS OUT
    CREDIT       A. V. HILL, 1923
    SPOKEN       Hill said the muscle runs out of oxygen. That is why you stop.

04  VIVEKA   light on the HEAD
    BOARD SAYS   THE OXYGEN IS STILL THERE
    CREDIT       TIM NOAKES, 1997
    SPOKEN       Then measure yourself the moment you stop. The oxygen is still there. So is the fuel.

05  MANAN    light on the LEG
    BOARD SAYS   THE MUSCLE FAILS
    CREDIT       A. V. HILL, 1923
    SPOKEN       So the muscle fails.

06  VIVEKA   light on the HEAD
    BOARD SAYS   THE MUSCLE IS TOLD TO STOP
    CREDIT       TIM NOAKES, 1997
    SPOKEN       The muscle is TOLD to stop. It is still able. It is being held back.

07  MANAN    light on the LEG
    BOARD SAYS   THE BODY BREAKS DOWN
    CREDIT       A. V. HILL, 1923
    SPOKEN       But Hill said the body breaks down. A catastrophe.

08  VIVEKA   light on the HEAD
    BOARD SAYS   THE BODY IS PROTECTED
    CREDIT       TIM NOAKES, 1997
    SPOKEN       Nothing breaks. You are being protected, and you feel that protection as tiredness.

09  MANAN    light on the HEAD
    BOARD SAYS   AND HILL HIMSELF

    SPOKEN       And Hill himself? Did he never think of this?

10  VIVEKA   light on the HEAD
    BOARD SAYS   HILL SAW IT FIRST
    CREDIT       A. V. HILL, 1924
    SPOKEN       He did. One year later, in 1924, he wrote that something central must be governing the heart, protecting it.

11  VIVEKA   light on the HEAD
    BOARD SAYS   BUT HE HAD NO EVIDENCE
    CREDIT       A. V. HILL, 1924
    SPOKEN       But he had only reasoning, no evidence. So it was dismissed, and for seventy years everybody studied the muscle.

12  VIVEKA   light on the HEAD
    BOARD SAYS   PROVED IN FIVE PAPERS
    CREDIT       NOAKES, ST CLAIR GIBSON AND LAMBERT, 2004
    SPOKEN       Then Noakes, St Clair Gibson and Lambert published it properly, five linked papers, in 2004.

13  VIVEKA   light on the HEAD
    BOARD SAYS   THE BRAIN DECIDES
    CREDIT       THE CENTRAL GOVERNOR
    SPOKEN       The brain reads your pulse, your breath, your temperature, your water, your sugar. The whole time. And it decides when you stop.

DIALOGUE_FOR_TTS.txt holds every spoken line in order, nothing else, one per
paragraph, ready to paste into a text to speech engine.

MANAN_LINES.md and VIVEKA_LINES.md hold one actor each: the name on the first
line, then only that actor's lines. Record one voice at a time without reading
the other half aloud by mistake.
