The AI post prompt is validated with `max:2000` on the backend, but the create form gave no hint of the limit — users could write past it and only find out via a validation error on submit. Add a live `X/2000` counter below the "What is this post about?" textarea. It turns red (`text-destructive`) once the prompt exceeds the limit, and the generate button is disabled while over it (`canSubmit` now checks `length <= PROMPT_MAX`), so the limit is caught before the request.
The counter added earlier drifted from the backend in two ways: it counted UTF-16 code units over the raw (untrimmed) value, while the backend measures Unicode characters (mb_strlen) over the trimmed value that is actually sent — so emoji or trailing whitespace could falsely turn the counter red and block the button. The 2000 limit was also copied into three places, and the wizard's frontend `>= 3` minimum had no backend counterpart. - Add App\Support\AiPromptRules as the single source of truth for the prompt bounds; both StartPostCreationRequest and GeneratePostContentRequest use it. - Add min:3 to the create wizard endpoint so front and back agree (the editor's generate-content flow keeps `required` — it has no counter to mirror). - Count code points over the trimmed value in AiPostWizard so the counter and the submit gate match what the backend validates, matching AltTextDialog. - Cover min/max/boundary in PostAiCreateTest.
…boundary - Assert GeneratePostContentRequest rejects a prompt over the shared max, so the editor's limit is pinned explicitly (not only implied by the create wizard). - Assert the create wizard accepts a prompt at exactly the minimum length, complementing the below-minimum rejection.
- Rename AiPromptRules::promptRule() to wizardPromptRule() so the asymmetry is explicit: only the create wizard carries a minimum; the editor's generation reuses just the shared maximum. - Add aria-live and a data-testid to the prompt counter so the over-limit state is announced to assistive tech and reachable from browser tests.

Problem
The AI post prompt is validated with
max:2000on the backend(
StartPostCreationRequest), but the create form gives no hint of that limit.Users can type well past 2000 characters and only discover the cap through a
validation error when they hit generate.
Change
A live character counter below the "What is this post about?" textarea in
AiPostWizard.vue:length/2000, right-aligned under the field.text-destructive) once the prompt exceeds the limit.canSubmitnow alsochecks
promptText.length <= PROMPT_MAX— so the limit is enforced in the UIbefore the request is sent.
PROMPT_MAXmirrors the backendmax:2000rule so the two stay in sync.Frontend-only, single file:
