A first step towards keeping style in CSS rather than inline. This adds Libraries/common.css and moves the styles repeated across the tool pages into it:

• the rule hiding Plotly notifications (in 14 pages' <style> blocks)
• the header table width and GitHub logo sizes (17 pages)
• the colour and underline of the title link (18 pages)

Pages render exactly as before. Screenshots of all 18 changed pages are pixel-identical to main. GeofenceGenerator has its own header layout and is left as is.

This also gives somewhere to put a dark theme, which I'll follow up with separately.

This CSS consolidation looks good: rendering is unchanged on all 18 pages in Chromium, and eslint passes on this head.

Minor (1)

• DFULoader/index.html:6 — the new common.css <link> is at column 0; the other <head> lines are indented 4 spaces. Optional tidy-up.

This CSS consolidation still looks good at af46562: computed styles match base on all 18 pages in headless Chromium, and eslint passes. Since the last review, the indentation of the common.css link in DFULoader/index.html:6 has been fixed, and there are no open findings.
