```javascript
function applyTheme(theme) {
var root = document.documentElement;
root.style.setProperty('--sf-body-bg', theme.bodyBg);
root.style.setProperty('--sf-board-bg', theme.boardBg);
root.style.setProperty('--sf-flap-top', theme.flapTop);
root.style.setProperty('--sf-flap-bottom', theme.flapBottom);
root.style.setProperty('--sf-gap-line', theme.gapLine);
root.style.setProperty('--sf-text', theme.text);
root.style.setProperty('--sf-author', theme.author);
}
```
--------------------------------
### Generate Theme Function
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html

```javascript
function generateTheme(hue, sat, mode) {
if (mode === 'dark') {
return { bodyBg: hsl(hue, sat, 6), boardBg: hsl(hue, sat, 10), flapTop: hsl(hue, sat, 18), flapBottom: hsl(hue, sat, 14), gapLine: hsl(hue, sat, 6), text: hsl(hue, Math.min(sat, 10), 94), author: sat === 0 ? hsl(45, 85, 60) : hsl(hue, 85, 72) };
} else {
return { bodyBg: hsl(hue, sat, 95), boardBg: hsl(hue, sat, 88), flapTop: hsl(hue, sat, 82), flapBottom: hsl(hue, sat, 76), gapLine: hsl(hue, sat, 70), text: hsl(hue, sat, 10), author: sat === 0 ? hsl(45, 85, 42) : hsl(hue, Math.max(sat, 40), 35) };
}
}
```

### Layout Quote for Split-Flap Display
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Calculates the grid and author row information for a given quote, fitting it within defined columns and rows. Handles padding and author markers.
```javascript
function layoutQuote(quote) {
var lines = quote.split('\n');
var grid = [];
var authorRows = [];
for (var r = 0; r < ROWS; r++) {
grid.push(new Array(COLS).fill(' '));
authorRows.push(false);
}
var usedRows = Math.min(lines.length, ROWS);
var startRow = Math.floor((ROWS - usedRows) / 2);
for (var l = 0; l < usedRows; l++) {
var line = lines[l] || '';
var isAuthor = line.charAt(0) === '@';
if (isAuthor) line = line.substring(1);
if (line.length > COLS) line = line.substring(0, COLS);
var pad = isAuthor ? (COLS - line.length) : 0;
if (isAuthor) authorRows[startRow + l] = true;
for (var ch = 0; ch < line.length; ch++) {
grid[startRow + l][pad + ch] = line[ch];
}
}
return { grid: grid, authorRows: authorRows };
}
```
--------------------------------
### HSL Color Helper Function
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
A utility function to format HSL color values into a CSS-compatible string. Used internally for theme generation.
```javascript

### Play Mechanical Click Sound
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Synthesizes a short, mechanical click sound using the Web Audio API. The sound's characteristics vary slightly with random parameters.
```javascript
function playClick() {
if (!soundEnabled || !audioCtx) return;
var duration = 0.012;
var now = audioCtx.currentTime;
var bufferSize = Math.ceil(audioCtx.sampleRate * duration);
var buffer = audioCtx.createBuffer(1, bufferSize, audioCtx.sampleRate);
var data = buffer.getChannelData(0);
for (var i = 0; i < bufferSize; i++) {
data[i] = (Math.random() * 2 - 1) * 0.3;
}
var source = audioCtx.createBufferSource();
source.buffer = buffer;
var filter = audioCtx.createBiquadFilter();
filter.type = 'bandpass';
filter.frequency.value = 3000 + Math.random() * 1000;
filter.Q.value = 1.5;
var gain = audioCtx.createGain();
gain.gain.setValueAtTime(0.08 + Math.random() * 0.04, now);
gain.gain.exponentialRampToValueAtTime(0.001, now + duration);
source.connect(filter);
filter.connect(gain);
gain.connect(audioCtx.destination);
source.start(now);
source.stop(now + duration);
}
```
--------------------------------
### Layout Quote Centering
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Arranges lines of a quote centrally on the display grid, with lines left-aligned and the author right-aligned.
```javascript
function layoutQuote(lines) {
var grid = [];
var authorRows = {};
for (var r = 0; r < ROWS; r++) {
var row = [];
for (var c = 0; c < COLS; c++) row.push(' ');
grid.push(row);
}
var usedRows = Math
```
--------------------------------
### Define Character Drum Sequence
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Defines the fixed sequence of characters available on the split-flap drum and creates an index for quick lookup.
```javascript
var drum = ' ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.,:;!?\'-';
var drumIndex = {};
for (var di = 0; di < drum.length; di++) drumIndex[drum[di]] = di;
```
--------------------------------
### Animate Drum to Target Character
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Simulates the physical drum rotation to reach a target character. It spins forward, decelerating as it approaches the target.
```javascript
function drumToChar(index, targetChar, baseDelay) {
cancelCell(index);
var fromIdx = drumIndex[currentChars[index]];
var toIdx = drumIndex[targetChar];
if (fromIdx === undefined) fromIdx = 0;
if (toIdx === undefined) toIdx = 0;
var steps = [];
var pos = fromIdx;
while (pos !== toIdx) {
pos = (pos + 1) % drum.length;
steps.push(drum[pos]);
}
if (steps.length === 0) return 0;
var minGap = 35;
var maxGap = 160;
var cumulative = 0;
for (var s = 0; s < steps.length; s++) {
var progress = s / steps.length;
var gap = minGap + (maxGap - minGap) * progress * progress;
var tid = (function(t, ch) {
return setTimeout(function() {
flipCell(index, ch);
}, baseDelay + t);
})(cumulative, steps[s]);
cellTimers[index].push(tid);
cumulative += gap;
}
return cumulative + FLIP_MS;
}
```

### Flip a Single Cell to a New Character
Source: https://github.com/hardikpandya/solari-split-flap/blob/main/index.html
Animates a single cell flipping from its current character to a new one. Includes visual and audio feedback.
```javascript
function flipCell(index, newChar) {
var cell = cells[index];
if (!cell) return;
var oldChar = currentChars[index];
if (oldChar === newChar) return;
var topChar = cell.querySelector('.flap-top .flap-char');
var bottomChar = cell.querySelector('.flap-bottom .flap-char');
var flip = cell.querySelector('.flap-flip');
var flipFront = cell.querySelector('.flap-flip-front .flap-char');
var flipBack = cell.querySelector('.flap-flip-back .flap-char');
flip.classList.remove('flipping');
flipFront.textContent = oldChar;
flipBack.textContent = newChar;
bottomChar.textContent = newChar;
void flip.offsetWidth;
flip.classList.add('flipping');
playClick();
var tid = setTimeout(function() {
topChar.textContent = newChar;
flip.classList.remove('flipping');
currentChars[index] = newChar;
}, FLIP_MS);
cellTimers[index].push(tid);
}
```

```javascript
var quotes = [
['FIRST LINE',
'SECOND LINE',
'',
'@AUTHOR NAME'], // @ prefix = yellow, right-aligned
['ANOTHER QUOTE',
'',
'@SOMEONE'],
];
```
