Finalize draft lessons (add missing circuit diagrams, workbench videos, media)

[jonfroehlich]

What

Several lessons carry a "This lesson is in draft form" callout banner near the top. Their prose is generally complete and followable, but they're missing circuit diagrams, workbench videos, and other media. This is a tracking issue so these don't fall further behind the polished V2.0 lessons.

This is the same root cause behind the "needs new media" pages flagged during the hero-media rollout — drafts have no climax demo to surface as a hero yet.

Draft lessons currently on main

• esp32/iot.md — missing circuit diagrams, images, videos
• advancedio/servo.md — content complete; circuit diagrams + servo-sweep workbench video not yet inserted
• esp32/capacitive-touch.md — WIP, missing ~4 diagrams + touch-piano climax demo (tracked in detail by ESP32 capacitive-touch: add 4 missing circuit diagrams #114)

Draft lessons on unmerged branch esp32-bluetooth (will join main when that branch merges)

• esp32/ble-intro.md
• esp32/ble-bidirectional.md
• esp32/bluetooth-serial.md
• esp32/bluetooth-web-serial.md

Housekeeping (apply to all draft pages)

• Standardize the draft-banner wording (currently varies: "There is/are missing …" vs. "circuit diagrams and videos have not yet been inserted")
• Ensure each draft page carries nav_exclude/search_exclude so the media-a11y CI gate skips it (per website-dev.md)

Per-lesson media shot-lists created (each has a desk-work vs. bench/capture checklist + a suggested hero & draft caption):

• Media: finalize Servo Motors lesson (advancedio/servo.md) #127 — Servo Motors (advancedio/servo.md) — live
• Media: finalize Internet of Things lesson (esp32/iot.md) #128 — Internet of Things (esp32/iot.md) — live
• ESP32 capacitive-touch: add 4 missing circuit diagrams #114 — ESP32 capacitive-touch (4 diagrams) — live, pre-existing
• Media: finalize Introduction to BLE lesson (esp32/ble-intro.md) #129 — Introduction to BLE (esp32/ble-intro.md) — on esp32-bluetooth branch
• Media: finalize Bidirectional BLE lesson (esp32/ble-bidirectional.md) #130 — Bidirectional BLE (esp32/ble-bidirectional.md) — on esp32-bluetooth branch
• Media: finalize Bluetooth Serial lesson (esp32/bluetooth-serial.md) #131 — Bluetooth Serial (esp32/bluetooth-serial.md) — on esp32-bluetooth branch
• Media: finalize Bluetooth Web Serial lesson (esp32/bluetooth-web-serial.md) #132 — Bluetooth Web Serial (esp32/bluetooth-web-serial.md) — on esp32-bluetooth branch

The four BLE/Bluetooth pages go live (and join the live draft list) when esp32-bluetooth merges.
