Named CalGray, CalRGB and Lab resources currently leave inline-image sample estimates unknown even though their component counts are fixed. Resolve those families as one, three and three components, including aliases and indirect parameter dictionaries. The estimate remains metadata-derived; no colour conversion, pixel decoding or profile decoding is added.
Add two focused test methods for real PDF resource lookup, row padding and unsupported/malformed descriptions. Bump the tool/package version to 0.3.0 and document the scope using PDF 32000-1 sections 8.6.5.2-8.6.5.4 and 8.9.7.
Validation: all 32 tests pass on Windows CPython 3.12 and 3.13 and from the installed 0.3.0 wheel. Six new subcases fail with the previous resolver. Wheel and sdist build successfully; installed source matches the committed module. Independent automated QA passed nine synthetic PDF/CLI cases, 225 arithmetic cases and 80 non-CIE compatibility controls.
No new corpus/adoption measurement or conformance claim. ICCBased, Separation and DeviceN remain unknown. AI assistance: developed and checked with OpenAI Codex; independent automated QA is not human review.
