USR369 reviewed the second, root-level Tech library set (windows.html, android.html, scripts.html, shortcuts.html, php.html, define.html at frontend/30-Tech/ root -- separate from the apps/ set fixed earlier this session) after I found real bugs in it: windows.html and android.html are byte-identical (android.html should have distinct content but doesn't), and scripts.html has scrambled title/answer pairs plus empty answer fields for the QA-A006/QA-W010-013 entries that were correctly recovered into the apps/ set today. USR369's decision: leave this second set as-is, not worth fixing since it's not the set actually being used. No changes made to any of these files. Two pre-existing PREVIOUS_ files in this same folder (PREVIOUS_scripts_07-24-26.html, PREVIOUS_index_07-24-26.html, dated before today's SOP-PAGE-HYGIENE.md) also left untouched pending this same 'leave it' call -- not cleaned up, flagged for awareness only.
