docs: put the logo on every page Five pages were missing the header block -- the ones written or rewritten during this pass rather than migrated from a repository that already had it.
docs: make the protocol pages user-facing Programming Protocols is now a plain description of what each protocol does and which chips it is for. Protocol ID and Protocol Flags are merged into it and deleted as separate pages. The implementation detail -- write algorithms, pulse widths, voltage routing, register constants, datasheet citations, the invariant matrix -- moves to PROTOCOLS.md in the firmware repository, linked from the top of the page. Pin Maps keeps the adapter wiring and the pin-21 warning a user acts on; the full per-family maps and shield wiring move to PINOUTS.md alongside it. Part numbers on the protocol page are now ones that actually resolve in the chip database -- the truth check caught W29C0xx filed under the wrong protocol, and several family prefixes and Dallas suffixes that were not real part numbers.
docs: cut the reference pages down to what a user needs Shield Revisions: replace the git-provenance inventory with a plain list of the real revisions and how to tell them apart. Drop the silkscreen alias table, the ADC band table and the investigation-history pointer. Capability matrix loses supported_protocol_ids, max_vcc_v and runtime_guard_gaps; notes now carry detection and jumpers. No modified or personal boards. Pin Maps replaces Pinout Safety Review and AT28C04 Adapter: socket pin maps for all 15 chip families generated from the pinout data, the DIP24 adapter reroute, and the shield's own pin and control-register assignments. Chip Database Fields replaces Infoic Field Dictionary: describes the Firestarter chip database rather than the upstream format. Protocol ID: protocol and what the algorithm is, nothing else. Protocol Flags: one bit/mask/meaning table, unknown bits included as unknown rather than guessed at. Package Details deleted -- its flags tables duplicated Protocol Flags and its own half was DIP-filter internals. SRAM and NVRAM Behavior deleted. Lockable PROMs keeps its family tables; intro tightened and tracking parameters stripped from the datasheet links.
