Search is case sensitive, but icons are all lower case

[ian-weatherhogg-refractiv]

on mobile the search field enter gets automatically capitalized, so effectively search doesn't work.
and if a user searches for "Amazon" they'll get no results.

suggested fix:
after line 116:
search = search.trim().toLowerCase()

and change line 324 to:
<input type="text"autocapitalize="off"
