docs: plate reader manual

[jwwojak]

Overview

This PR migrates the plate reader instruction manual to MkDocs.

RTC-783

Test Plan and Hands on Testing

Check for grammar, style, and closely match the original source.

Changelog

Manual reog (minor)

Some sections of the original PDF were very short and looked weird as standalone pages. These have been moved into the "Product Specifications" section. Specifically, these:

• Measurement specs
• Detection wavelengths
• Status light
• Input/output (the power specs)

New CSS

Added to shared/instruction-manual.css. This creates a status dot that shows a 🌈 or color spectrum for one of the dots. The reader LED has a status that shows multiple colors.

/* Creates dot with red to blue spectrum lines. See plate reader LED table. */

.status-dot.rainbow {
  background-image: linear-gradient(to right, red, orange, yellow, green, blue);
  background-color: transparent; 
}

Code called in LED status light table:

<tr>
      <td><span class="status-dot-container"><span class="status-dot rainbow"></span>Various</span></td>
      <td>Solid</td>
      <td>Initialization/measurement in progress. The status light color corresponds to the selected light wavelength used for analysis.</td>
    </tr>

Which produces this:

Detection wavelengths text

This short section lists the wavelengths the module uses for detection. I added color codes to the text in parenthesis (red, green, blue, etc.) to match the wavelengths. Thought that might be a neat touch. Can remove. See specifications.md, section starts on line 97.

Review requests

Short manual. Shouldn't be much to review.

Risk assessment

Low, docs change only.
