[BUG] [v0.0.7] interpolate_brain_pulse and brain_cyan hardcode wrong RGB values — #00FFFF instead of CYAN_PRIMARY #00FFA3 (style.rs:449)

[anticsdecoded]

Description

In cortex-core/src/style.rs, the interpolate_brain_pulse() function claims to interpolate between CYAN_PRIMARY, SKY_BLUE, and ELECTRIC_BLUE (per its doc comments), but hardcodes completely different RGB values from those constants. Similarly, brain_cyan() uses the wrong blue channel value.

This produces wrong visible output: the ThinkingIndicator widget (which calls brain_pulse()) renders in blue-cyan #00FFFF instead of the project's intended green-cyan #00FFA3.

Proof of mismatch

The project constants at style.rs lines 13-19:

pub const CYAN_PRIMARY: Color = Color::Rgb(0, 255, 163);     // #00FFA3
pub const SKY_BLUE: Color = Color::Rgb(100, 255, 180);       // #64FFB4
pub const ELECTRIC_BLUE: Color = Color::Rgb(50, 255, 150);   // #32FF96

The brain widget at brain.rs line 66 uses the correct value:

const ACCENT_GREEN: (u8, u8, u8) = (0x00, 0xFF, 0xA3);  // = CYAN_PRIMARY ✓

But interpolate_brain_pulse() at style.rs lines 454-456 hardcodes wrong values:

// CYAN_PRIMARY:   RGB(0, 255, 255)     #00FFFF  ← WRONG (actual: 0, 255, 163)
// SKY_BLUE:       RGB(135, 206, 235)   #87CEEB  ← WRONG (actual: 100, 255, 180)
// ELECTRIC_BLUE:  RGB(125, 249, 255)   #7DF9FF  ← WRONG (actual: 50, 255, 150)

And brain_cyan() at style.rs line 437:

// CYAN_PRIMARY is RGB(0, 255, 255)  ← WRONG comment, actual is (0, 255, 163)
let bl = (255.0 * b) as u8;         // ← should be (163.0 * b)

The hardcoded values are standard web colors (CSS cyan, sky blue, electric blue) instead of the project's custom green-cyan palette.

Error Message

No crash — produces wrong visual output. The ThinkingIndicator shows blue-cyan pulsation instead of the project's green-cyan theme.

Debug Logs

User-visible call path:

ThinkingIndicator::render() (thinking.rs:84)
  └→ CortexStyle::brain_pulse(intensity) (style.rs:412)
       └→ interpolate_brain_pulse(intensity) (style.rs:449)
            └→ Returns colors like RGB(0, 255, 255) = #00FFFF
               instead of CYAN_PRIMARY = RGB(0, 255, 163) = #00FFA3

The brain widget itself (brain.rs) correctly uses ACCENT_GREEN = (0, 255, 163), so the ThinkingIndicator spinner shows a different color from the brain it accompanies.

System Information

Bounty Challenge System Information
====================================
Version: 0.1.0
OS: Windows
Version: Microsoft Windows [Version 10.0.26200.7840]
Rust: rustc 1.90.0
Target: x86_64
====================================

Steps to Reproduce

1. Look at the ThinkingIndicator widget with a pulse active
2. The spinner text pulses through blue-cyan tones (#00FFFF → #87CEEB → #7DF9FF)
3. Compare with the Brain widget next to it — Brain uses green-cyan (#00FFA3)
4. The two widgets that should share the same "brain" color scheme show different colors

Or verify programmatically:

// brain_pulse(0.0) should match CYAN_PRIMARY
let pulse_color = interpolate_brain_pulse(0.0);
assert_eq!(pulse_color, CYAN_PRIMARY);  // FAILS!
// pulse_color = Rgb(0, 255, 255)
// CYAN_PRIMARY = Rgb(0, 255, 163)

Expected Behavior

brain_pulse() should return colors interpolated between the actual constant values: CYAN_PRIMARY RGB(0,255,163), SKY_BLUE RGB(100,255,180), ELECTRIC_BLUE RGB(50,255,150).

Actual Behavior

brain_pulse() returns colors interpolated between wrong web-standard values: RGB(0,255,255), RGB(135,206,235), RGB(125,249,255) — producing blue-cyan output instead of the project's green-cyan theme.
