garrytanandcapy-ai[bot] df6cd725c2 design-lint: second review cycle
Waivers settle once per page after both tiers, so a blocking rule only the
render tier suspects is waivable and one it measures is refused; a claim in a
stylesheet answers for that stylesheet on every page that links it (no
shared-word check), so a sheet shared by two pages is no longer waived on one
and refused on the other. Every printed field is one line with control
characters stripped; the waiver regex is linear and ends at a carriage
return; a root-relative href cannot climb out of the lint root. The ancestor
map closes optional end tags implicitly and pops to the matching open tag, so
unclosed <li> no longer makes it quadratic. The static tier reports outline:
none with no ring anywhere as missing-focus-visible at its line;
literal-outside-tokens needs a --color-* or --font-* token to exist; the
banned gradient includes indigo-to-violet; a new banned-font rule reads
gstack's BANNED_FONTS; MONO_FACE matches whole words; bold keywords and
tokens count as weight 700 for the contrast threshold. stylesFor reads only
the entries that can match; glOcclusion memoises the pinned walk; the
confirm screenshot is taken at 1x; a page that throws in the render tier is a
render finding and the CLI exits 3 on an internal error. Docs name the token
conventions and what the lint does not cover.

// gstack-design-lint — the free, deterministic design lint behind /design-html
// and /design-review. Static tier over .html .css .jsx .tsx .vue .svelte .astro
// (Tailwind class strings included); --render measures the page in gstack's own
// browser (Aside first, the browse daemon otherwise).
//
// Usage: gstack-design-lint <file-or-dir ...> [--render] [--url <http://…>]
// [--scope page|component] [--job <job>] [--json] [--rules]
//
// Prints one "LINT: <blocks|ask|polish|waived> <rule-id> <file>:<line> <evidence> | fix: <fix>"
// line per finding, then "LINT_SUMMARY: blocks=N ask=N waived=N polish=N render=<ran|skipped: reason>".
// Exit 2 on blocks, 1 on unanswered asks, 0 otherwise; 3 on a usage error.
// docs/design-lint.md is the contract.
