feat: IPv6 CIDR support + true PPTX slide rendering - #209
Merged
Conversation
Parse IPv6 addresses/prefixes with BigInt: network, first/last address, total addresses, plus RFC 5952 compression and full-form expansion. The calculator now auto-detects IPv4 vs IPv6 by address family.
Rewrite the PPTX reader to recover each shape's position and size (EMU to px), styled text runs (size, bold, italic, color, alignment) and images, resolving inherited placeholder geometry from the slide layout. The viewer now draws slides at their actual positions instead of a flat text list.

Two follow-up upgrades to tools shipped earlier today:
1. IPv6 in the CIDR Calculator — the calculator now auto-detects IPv4 vs IPv6 and, for IPv6, computes the network, first/last address and total address count with BigInt, plus RFC 5952 compression and full-form expansion (handles
::and embedded IPv4). Unit-tested.2. True PPTX slide rendering — rewrote the custom OOXML reader (license-clean, no third-party renderer) to recover each shape's real position/size (EMU→px), styled text runs (size, bold, italic, color, alignment) and images, resolving inherited placeholder geometry from the slide layout. The viewer now draws slides at their actual layout (scaled to fit) instead of a flat text list. Text is React-escaped (XSS-safe). Charts/SmartArt/effects remain out of scope. Unit-tested.
